The strategic role of optical technology in the Networked Society
Sandor Albrecht
Ericsson Research - Sweden
abstract: We are on the brink of an extraordinary revolution that will change our world forever. In this new world, called the Networked Society, everyone, everything and everywhere will be connected in real time. The way we innovate, collaborate, produce, govern and achieve sustainability will be fundamentally changed. To achieve this, not only the entire population of the planet but tens of billion devices, with a plethora of requirements associated to the different services will be connected. The network will serve as a common platform for all kinds of activities, as well as a foundation for innovation and transformation.

This will put extreme demand on the network: a massive growth of traffic volume and huge number of connected devices with a wide range of requirements and characteristics. To achieve this, optical technology is expected to play a crucial role. While nowadays optical technologies are mostly considered in the metro and backbone segments of the network, in the future it will be key in other segments, e.g. access, closer to antennas, fronthaul or the data center interconnections. Moreover, optical will play a key role in interconnection of systems, rack-to-rack, board-to-board and chip-to-chip, which will have to reach huge level of data processing at lower cost, footprint and power consumption.

In this talk, we describe the requirements of the Network Society and give examples of new optical solutions and photonics technologies to assure connectivity with the desired level of performance, characteristics and costs.

Optical Interconnects and Computing of the Future: Point of View in Lasers and Photonic Integrated Circuits
Matsuo Shinji
NTT - Japan
abstract: The electrical power consumed in data transmission systems is now hampering efforts to further increase the speed and capacity at various scales, ranging from microprocessors, servers, and routers to data centers. Optical interconnects employing an ultralow energy directly modulated lasers will play a key role in reducing the power consumption. Since a laserâ€TMs operating energy is proportional to the size of its cavity, developing high-performance lasers with a small cavity is important. For this purpose, we have developed membrane DFB and photonic crystal (PhC) lasers with a buried heterostructure (BH). Thanks to the reduction of cavity size and the increase in optical confinement factor, we have achieved extremely small operating energy of less than 5 fJ/bit with a PhC wavelength-scale cavity. Heterogeneous integration with Si photonics devices is also important because device fabrication using Si CMOS technologies is promising for reducing device cost. Furthermore, to construct high-capacity and cost- efficient photonic networks in datacom and computercom, wavelength division multiplexing (WDM) technologies are strongly required because a flexible network can be constructed.

Here we review recent progress in this field, focusing on ultralow-power-consumption directly modulated lasers and their photonic integrated circuits. We also describe progress in heterogeneous integration of these lasers and Si photonics devices.

This will put extreme demand on the network: a massive growth of traffic volume and huge number of connected devices with a wide range of requirements and characteristics. To achieve this, optical technology is expected to play a crucial role.

Large-Scale Integrated Classical and Quantum Photonics for High-Performance Switching
Ray Beausoleil
Hewlett-Packard Company - USA
abstract: Moore's Law has set great expectations that the performance/price ratio of commercially available semiconductor devices will continue to improve exponentially at least until the end of this decade. Although the physics of nanoscale silicon transistors alone could allow these expectations to (almost) be met, the physics of the metal wires that connect these transistors places stringent limits on the performance of integrated circuits. We will describe a Si- compatible global interconnect architecture --- based on chip-scale optical wavelength division multiplexing --- that could precipitate an "optical Moore's Law" and allow exponential performance gains until the transistors themselves become the bottleneck. Based on similar fabrication techniques and technologies, we will also present quantum approaches to optically-coupled information processors for computation beyond Moore's Law. First, we will briefly review our recent results demonstrating the optical coupling of nitrogen-vacancy color centers to single-crystal diamond resonators, allowing enhancement of the zero-photon transition rate by a factor of 70. This is a first critical step towards large-scale integrated diamond quantum optical networks, but scaling remains a formidable challenge for the development of practical applications of quantum information technology for commercial utilization. Second, it may be possible to harness devices with explicitly quantum coherent behavior to perform reliable classical computations using quantum feedback control. As an initial step toward this goal, we have demonstrated ultrafast switching in microscale nonlinear optical devices fabricated in amorphous silicon and gallium arsenide, and we have developed a semi-quantum photonic circuit simulator to guide us as we layout photonic circuits with hundreds of coherently interacting elements.

Organizers: Clint Schow (UCSB - USA) & Dominique Chiaroni (ALU Bell Labs - France)
Pontevecchio room


Session 1: Photonics systems for intra-data centers

Chair of the session 1: Clint Schow, UCSB

Abstract: Datacenters represented more than 51% of the energy consumption of the worldwide ICT in 2013. It is expected that the energy consumption of data centers will continue to grow and dominate. It is then mandatory to investigate new approaches and new technologies to reduce the energy consumption of data centers. Optical technologies have a high potential to increase the energy efficiency in particular by exploiting the WDM dimension. Typically we distinguish three main layers in a data centers: the racks of servers, the interconnection and aggregation layer and the load balancers plus the border router layer. Thus this workshop by addressing different technologies that could be adapted to any of these three layers, will draw a cartography of potential approaches to effectively reduce the energy consumption of data centers.

16h30 - 16h45: Introduction (Clint Schow and Dominique Chiaroni)
Abstract: This first presentation will first describe the energy consumption evolution of data centers in ICT. Different challenges to cover all the segments of a data center will be then described to introduce the different talks of this workshop.

16h45 - 17h00: Optical Switching in Data Centers, Prof. George Papen and Prof. George Porter, UCSD, gpapen@ucsd.edu
Abstract: We discuss the challenges of using optical switching in large-scale datacenters addressing both the physical requirements of the optical switch as well as aspects of the control plane, which must coordinate the optical switching with standard switching technologies such as packet switching.

17h00 - 17h15: High performance optical circuit switching for software- defined datacentre networks, Dr. Nick Parsons, Polatis Ltd, Cambridge, UK, nick.parsons@polatis.com
Abstract: DirectLight is a well-established dark fibre optical circuit switch platform offering currently up to 192x192 fibre ports with typical loss and switching speed of 1dB and 20ms, respectively. This talk reviews the performance and scalability of DirectLight for dynamic reconfiguration of the fibre layer in energy-efficient software-defined data centre networks.

17h15 - 17h30: Highly-Scalable Torus Data Center Network with Diversified Transmission Schemes, Salah Ibrahim, Toru Segawa, Tatsushi Nakahara, Hiroshi Ishikawa, Atsushi Hiramatsu, Yue-Cai Huang, Ken-ichi Kitayama, and Ryo Takahashi, NTT, t.ryo@lab.ntt.co.jp
Abstract: We review a highly-scalable Torus DC network in which multiple transmission schemes are enabled to support service diversity, where the optical packet, circuit and virtual circuit switching schemes all coexist on the same hardware platform based on the deployment of hybrid optoelectronic routers (HOPRs) and centralized network controller.

17h30 - 17h45: Scalability of fast silicon photonic switches, Nicolas Dupuis, IBM, ndupuis@us.ibm.com
Abstract: Silicon photonics is an attractive technology for designing low-power and dense footprint photonic switches with nanosecond-scale reconfiguration time. The integration of optical gain into the switch fabric has the potential to improve the scalability of the technology but the optical crosstalk remains a major challenge that needs to be addressed.

17h45 - 18h00: Hybrid integration of WDM transceivers for short reach applications including inter-DC and intra-DC, Mark Earnshaw, Bell Labs, mark.earnshaw@alcatel-lucent.com
Abstract: Growth of data centers in number and scale is driving demand for higher capacity, higher density and lower cost optical transceivers. WDM offers the potential to dramatically scale the capacity of optical interconnects but breakthroughs are needed in simplifying the cost and complexity of traditional WDM transceivers as used in long-haul and metro telecom networks.

Session 2: Round table on "Research directions for intra data centers"

Chair of the session 2: Dominique Chiaroni, Bell Labs

Abstract: This round table will recall the challenges and the different solutions. The objective of this round table is to exchange with the audience to have a fruitful discussion on this topic and identify some robust directions for photonics in switching.

18h00 - 18h30: Panelists of the round table: Ibrahim Salah (NTT), Nicolas Dupuis (IBM), Mark Earnshaw (Bell Labs), Nick Parsons (Polatis), George Papen (UCSD)

Workshop Motivation

The traffic carried by core optical networks as well as the per-channel interface rates required by routers are growing at a remarkable pace of typically between 30 and 60% year-over-year. Optical transmission and networking advancements have so far satisfied these traffic requirements by delivering the content over the network infrastructure in a cost and energy efficient manner. However we are approaching fundamental spectral efficiency limits of single-mode fibers and the growth capabilities of conventional WDM networks operating on a fixed frequency grid are quite limited. New optical networking solutions need to be identified to resolve this situation.

Workshop Focus

A large number of significant innovations that are able to offer a capacity increase practically by a factor of around 10-20 (compared to legacy WDM systems at 10 Gb/s on a 50-GHz spacing) have emerged over the last couple of years. Initial efforts targeted innovative modulation/coding techniques and flexible frequency allocations, in an effort to increase the spectral density in optical fiber links, leading eventually to the definition of spectrally flexible/elastic optical networks utilizing optical superchannels together with spectrally flexible/elastic multiplexing schemes (e.g. OFDM and Nyquist WDM), and advanced modulation formats which enable the dynamic and adaptive allocation of end-to-end demands with variable connection characteristics (e.g. requested data rates). However, while the spectrally flexible/elastic super-channel approach can optimize network resources through increased spectral utilization, it has limited growth potential due to the nonlinear Shannon limit imposed on the transport capacity of single-mode optical fiber within the limited gain bandwidth of optical amplifiers. Multi-band amplification technologies (e.g., C+L+S-band amplifiers) may yield temporary relief, but the only evident long- term solution to extend the capacity of optical communication systems relies on the use of the spatial domain. The simplest way to achieve spatial multiplexing is to deploy multiple systems in parallel. However, by simply increasing the number of systems, the cost and power consumption also increases linearly. In order to limit the increase in cost and power consumption, component sharing and integration have to be introduced. To this extent, significant research efforts have focused on the development and performance evaluation of few-mode fibers (FMF) and multi-core fibers (MCF), which can be seen as 'integrated fiber' media, for space division multiplexed (SDM) systems. This line of work is further supported by the development of integrated optical amplification systems, as well as the significant development efforts in the field of Tb/s integrated transponders for SDM systems. For such systems, the use of spatial superchannels, which are groups of same-wavelength sub-channels that are transmitted on separate spatial modes but routed together, are being investigated.

The vast majority of efforts so far on the aforementioned topics focus on point-to-point transmission systems and not so much on networking aspects. There should be a need for development of novel switching schemes in order to explore the full potential of these spatially and spectrally flexible optical networks. Switching schemes should be able to support joint or independent switching of sub-channels out of spatial and/or spectral super-channels.

Workshop Aim

This proposed PS'15 Workshop aims to provide a forum where experts from all over the world will provide to the audience a comprehensive overview of the state-of-the- art for "Photonic Switching Systems in support of Spatially and Spectrally Flexible Elastic Optical Networking". The talks will provide information about the current research challenges and directions as well as insights into the projected commercial needs for this emerging scientific area of optical networking. The symposium on these topics is expected to attract many participants who will engage also in lively discussions with the speakers and panelists.

16:30-18:30 WS4 - What photonics for 5G? Optical technologies, systems an networks for 5G

Organizer : Fabio Cavaliere (Ericsson, ITA)
Franciabigio room

16:30:16:36 Introduction
Fabio Cavaliere, Ericsson, fabio.cavaliere@ericsson.com

16:36-16:48 Impact of 5G environment on operators optical infrastructures and equipment
Alessandro Percelsi, Telecom Italia, alessandro.percelsi@telecomitalia.it

With respect to the 3G/4G monolithic design focused on mobile broadband with defined and static connection requirements, the 5G network architecture is expected to be very flexible to efficiently support a lot of use cases with different needs. Operators and vendors are looking for flexible and software-defined configuration of all networking elements included in the RAN and packet core network, to provide such a diversity with reasonable cost. The NFV and SDN approach used in the data-centers should be adapted to the optical transport network, where new optical technologies like flex-transceivers and on-demand connection setting could be used to provide an unified agnostic transport for different services of the 5G environment. Reusing and sharing of optical infrastructures and accommodating the legacy mobile solutions are also mandatory for operators

16:48-17:00 Flexible and cost efficient optical 5G transport networks
Prof. Lena Wosinska, KTH Royal Institute of Technology, wosinska@kth.se

5G mobile communication is seen as the enabler for the networked society where connectivity will be available anywhere and anytime to anyone and anything. The details of 5G are the subject to ongoing research and debate, mostly focused on understanding radio technologies that can enable the 5G vision, while the implications on transport is not widely considered yet. However, with continued site densification and with growing number of different services to be provisioned, the role of the transport network, i.e., the backhaul of radio base stations or fronthaul of remote radio units, is becoming more and more crucial.
This talk will discuss a number of data plane architectures able to provide a flexible and cost efficient optical transport solution for 5G. A number of architectural options (i.e., all optical vs. intermediate electronic processing, with and without caching) for a 5G-transport network will be compared with the objective of identifying the most promising alternatives in terms of total power consumption and equipment cost.

17:24-17:36 5G and optics: a winning combination
Stefano Stracca, Ericsson, stefano.stracca@ericsson.com

We are evolving towards the networked society, and 5G will be the driver for that. Setting apart from previous mobile generations, 5G will see photonic technologies and optical networking perform a fundamental role in it, side by side with new radio access technologies, network virtualization functions and cloud solutions in an closely interdependent structure. This leads to great opportunities and big challenges, forcing to abandon traditional disciplinary and network segment partitioning approaches. Some relevant examples of research activities regarding photonic technologies and optical networking in 5G are presented.

17:36-17:48 Photonic component technology for 5G networks
Dr. Thomas Sommer, OCLARO - USA

The growth of the mobile internet is a critically important factor in emerging communications systems architectures and poses numerous challenges in all aspects of the network, from the connection to the base station itself through to high-capacity data transport in the core network. We review some of the key photonic component technologies which are being developed to address these demands, ranging from fronthaul/backhaul links for cellular base stations, employing new architectures such as tunable laser-based WDM over passive optical networks, through to high bandwidth coherent transmission at 100Gbit/s and above in the metro and core network segments.

17:48-18:00 Switch to integrated Microwave Photonics
Paulus W.L. van Dijk, Satrax B.V., p.w.l.vandijk@satrax.nl

Integrated microwave photonics (IMWP) is a novel field in which the fast-paced progress in integrated, on-chip, optics is harnessed to provide breakthrough performances in well-established microwave photonic processing functions, which are traditionally realized using discrete optoelectronic components. A field where IMWP can have a strong impact is the one of Antenna Arrays for 5G networks. Such arrays offer a number of attractive characteristics, including a conformal array profile, electronic beamforming (beam shaping and beam steering), interference nulling and the capability to generate multiple antenna beams simultaneously. In many cases, however, the performance of a phased array is limited by the characteristics of the beamforming network (BFN) used. It is generally desired to realize beamformers with broad instantaneous bandwidth, continuous amplitude, and delay tunability and, at the same time, capable of feeding large arrays. This, however, is very challenging to achieve using only electronics. For this reason, the last few years, an increasing amount of research has been directed to beamforming in the optical domain using, integrated microwave photonics solutions. Apart from Antenna Array applications, opportunities for cost effective use of IMWP in switched delay lines has become feasible due to the continuous improvement of the optical chips, particularly the achieved record-low propagation losses in Si3N4/SiO2-based-chips combined with the high integration density.

18:00-18:30 Panel discussion
Fabio Cavaliere, Ericsson, fabio.cavaliere@ericsson.com

9:00 - 18:30 Tyrrhenian International Workshop on Digital Communications 2015: Fiber Nonlinearity in Coherent Optical Communications

General Chair: Enrico Forestieri, Scuola Superiore Sant'Anna, Italy
Technical Program Committee Chair: Marco Secondini, Scuola Superiore Sant'Anna, Italy
Pitti room

Abstract: The quest for higher spectral efficiency and data rate made possible by coherent techniques has to face the problem of fiber nonlinearities. Today, any design based on advanced techniques requiring knowledge of the statistical properties of the received signal is carried on either by simply neglecting the ensuing of nonlinearities or on simplifying assumptions. Moreover, major conferences on optical communication are generally focused on technological rather than theoretical aspects. This workshop aims at laying special stress on in-depth theoretical investigation about the impact of fiber nonlinearities in coherent optical communication systems.
