WS – Multimode photonics: optical waveguides, components and systems

 

Organizers

Sergio G. Leon-Saval University of Sydney, Australia

Marco Santagiustina University of Padova, Italy

 

Abstract:

It has been relatively recently when more photonics applications are exploiting optical modal properties and interactions of few-mode and multicore waveguides and systems. This trend towards the use of multimode and multicore devices has to be accompanied by new enabling technologies and applications that will allow exploiting the full potential of multimode photonics. The importance of multimode photonics is also emerging in long-haul telecommunications as a possibility for overcoming the capacity crunch of single-mode optical fiber communications.

This Workshop intends to give awareness and an update on the state of the art on multimode photonics technologies, from the optical waveguides, component and systems to their applications. The other important aim of this workshop is also to engage the broader photonics and telecommunications community to debate on the application fields of multimode photonics.

WS – How should we design optical communication networks with flexible DSP based transceivers?

Abstract:

Supporting the increasing data transport requirements, in a cost effective way, is the major challenge facing optical communications researchers and network providers. The recent increases in transport capacity that have been witnessed, have come as a result of increased digital signal processing at the transmitter and receiver enabling higher dimensional coherent modulation formats, along with the adoption of forward error correction coding. In addition to this one of the key advantages that we have in optical fiber communications over, for example, wireless communications is the ability to engineer the channel to optimize the network performance.

Recently there have been a number of the developments where the fiber channel has been engineered to increase capacity. For example, ultralow loss fibers, to increase reach, multicore and few mode fibers, that attempt to increase the capacity of a single fiber, or hollow core fibers to reduce the nonlinear effects. New amplifier techniques, such as hybrid Raman EDFA have also been demonstrated to provide greater bandwidths whilst maintaining flat gain. Coherent reception and DSP has enabled transceivers that are able to compensate for transmission impairments and optimize the modulation format to match the channel. FEC has been extensively deployed to increase reach and system margin.

However in the design of optical communication systems and networks these three areas: channel, transceiver and FEC, are often considered separately.

The new paradigm of Software defined transceivers where DSP allows the modulation, demodulation and coding to be adapted to the channel, has the potential to dramatically change the way that we design optical communication systems and networks.

This workshop aims to bring together experts in: DSP for higher order modulation formats, information theory and error correction, optical fiber design, propagation, amplification and network design in order to consider the fiber communications system in a holistic way to try and answer the question:

“How should we design optical communication networks with flexible DSP based software defined transceivers?”

Abstract:

The future generation of wireless communication systems (5G) must be able to provide efficient high-performing connections for a wide range of different services, from mobile broadband communications to instantaneous data sharing and the Internet of Things. These heterogeneous communications will define a wide range of requirements and characteristics in terms of data rates, latency and reliability. A massive 1000-fold growth in traffic volume is expected, and it will be deployed over several different frequency bands, in particular in the millimetre-wave band range (> 30 GHz) where fractional bandwidths of several GHz are available. A heavy spatial reuse of frequencies will be sought by means of precise beamforming with large antenna arrays. The envisioned scenario poses serious technological challenges for future wireless networks, including the containment of energy consumption and cost, which cannot be solved by improving today’s systems. A technological breakthrough must therefore be sought.
This workshop aims at envisaging and exploring photonics as a new technology for RF communication systems. It will highlight the issues of current wireless communications, the role that photonics can play in overcoming these issues and enabling a novel paradigm of software-defined multiprotocol radio systems. The workshop wants to represent a significant overview of the state of the art of radio-over-fiber systems and subsystems as well as available technologies for optical devices in these applications. Moreover it will envisage the future development of Microwave Photonics in the industrial perspective.

WS – Optical technologies for the exascale cloud datacenter era

Abstract:

The transition into a content-centric internet model is fuelling a relentless growth of datacenter traffic over a 25% CAGR trajectory that is expected to bring global annual datacenter IP traffic to a sheer 7.7 ZB by 2017, up from 2.6 ZB in 2012. The largest portion of this traffic (76%) resides within the datacenter, while the emerging disaggregated-datacenter model is expected to further increase this trend, posing inordinate challenges to traditional datacenter network technologies. The most daunting one is scalability; traditional “fat tree” architectures scale super-linearly with the number of servers, imposing a ceiling on the maximum economically-viable datacenter dimensions.

The increasing deployment of optical technologies for rack-to-rack communication in current generation datacenter and HPC systems has so far led to faster and greener system implementations, but is not sufficient to sustain performance trends and contain energy consumption. Photonics have started to migrate into all levels of the interconnect hierarchy as an enabler of future datacenter architectures, in order to meet the rapidly growing demand on digital information transmission, capture, storage and processing.

Motivated by recent breakthroughs and emerging technologies in short-reach optical interconnects and the evolution of datacenter architectures, this workshop aims to highlight the latest achievements on system-integrated optical interconnects, that are placing photonics among the key enabling technologies of datacom and computercom evolution.

WS – SDN & NFV: Real value with new business opportunities or research hype with unmanageable complexity?

Abstract:

Network programmability based on Software-Defined Networks (SDN) and Network Function Virtualization (NFV) is a major trend in optical network research and standardization. After the initial focus on the OpenFlow protocol as a new southbound interface to directly control the forwarding plane of packet switches, SDN is gaining increased importance as new networking paradigm allowing virtualization and programmability based on hardware abstraction and open programming interfaces. New SDN architectures and protocols are being proposed and discussed in the IETF, e.g. northbound protocols for topology dissemination and service orchestration. NFV is increasing the flexibility even further by moving network functions from dedicated hardware to virtual machines. This new degrees of flexibility pose opens a set of new challenges and research issues, ranging from service orchestration, security, reliability, monitorability, etc.

The open questions is, if and how SDN and NFV can simplify the way optical access and core network are operated.

This workshop will bring together views from ongoing research projects (e.g., STRAUSS, IDEALIST, DISCUS, COMBO) as well as Industrial actors (both network operators and vendors) on hot topics and current trends in SDN and NFV. The topics will be presented in the form of invited talks of 15 minutes. A moderated panel discussion both for research and industrial will deal with the controversial topics that can be also discussed together with the audience.

WS – Fibre access and core network evolution: what are the next steps towards an integrated end-to-end network?

Abstract:

While FTTH is widely recognized as the ultimate goal of access network upgrade, the path towards its realization seems to differ among network operators, some of them planning direct FTTH deployment, while others considering intermediate steps such as FTTCab or FTTCurb. In addition, due to the large increase in available bandwidth that new access technologies will bring, it becomes of paramount importance to understand how the network core should evolve to support such increase in user bandwidth. Recent studies point at end-to-end solutions, based on seamless integration of access and core as a means to develop architectures that are sustainable from a cost and energy consumption perspective, while providing the necessary capacity and flexibility to support forthcoming services and applications.

This workshop will provide a discussion on the access, core evolution and end-to-end network architecture with two main objectives. The former is to identify the drivers for the different operators, pushing them towards different evolution plans both in the access and core development. The latter is to understand which are the current plans for network upgrading and towards a tighter integration of access and core networks, as well as which are the challenges and potential solutions for evolution towards next-generation architectures.

A main outcome of the workshop will be also to get an idea of the rationale behind the choices from different operators and vendors, whether there are common issues, misconceptions, etc.
