Increasing the functional unit numbers, density, and diversity on chip has long been a goal in the development of integrated photonics. Major progress came from the development of III-V integrated photonics for communication applications. However, Si photonics has seen much progress and promises new applications. Hybrid approaches further complicate the development of VLSIP and scaling methods from a foundry and supply chain perspective. At the same time new applications are emerging in the areas of IoT and 5G wireless that are demanding more from optical devices and systems in cost and energy sensitive regimes that require integration.

The first half of this workshop will examine the current state of large-scale integration across multiple integrated photonic platforms and examine the current and emerging application drivers, including what future applications are motivating larger scale integration and which have the potential market size to support VLSIP. It will then explore the challenges to realizing VLSIP related to fabrication, foundry support, and supply chains across the multiple technology and integration platforms.

Modelling has been the cornerstone of advances in fibre systems, from understanding our devices to untangling transmission effects at any and all distances. The discoveries that push communications speeds and reach, also challenge our ability to understand and anticipate the implications of adopting each new technique.

We will explore in this workshop, both the changes driving the need for new models, and the disruptive application of machine learning to supplant even the idea of modelling. Transmission systems spanning 100s of nm, exploiting dozens of spatial modes in exotic fibres, with DSP that unknots correlations in nonlinear effects, and all at transoceanic distances are under investigation. These are the advances that challenge models for fibre transmission. How do we capture Raman effects in UWB transmissions, acoustic Brouillon scattering in undersea cables, quantum capacity limits, and more? Device designs and system architectures must be optimised to maximise capacity.

Adopting silicon photonics brings low cost, but optical components behave differently when born on a CMOS platform. SOAs are old friends, but how will they react when we push them to cover UWB? Should we model these devices & systems, or should we let a machine help us to maximise capacity instead? We will bring together experts to share their views on emerging challenges in modelling as a tool to ever improved optical communications.

Neuromorphic computing is a signal processing technology which mimics neuro-biological architectures in the brain. Neuromorphic signal processing has potential in the applications of generation, equalisation or detection of signals with the perspective benefit of a significantly higher power efficiency than today’s digital signal processing (DSP) technology. Neuromorphic computing or processing approaches are based on analog signal processing with electrical or optical signal, partly digital or asynchronous processing, ranging from emulation of spiking neuron to analog computation of artificial neural network and reservoir computing.

New generation of brain-inspired signal processing algorithms as well as recent advances in development of new materials and novel architectures enabled a surge in optical implementation of machine learning methods. This has become a rapidly growing area. Recent achievements include, for instance, demonstrations of optical neural networks implementing speech recognition and mitigation of distortions in optical communications. Different technological avenues are being pursued, including bulk and integrated optics, while several start-ups have been recently created to exploit these opportunities.

The aim of this workshop is to bring together leading experts in photonics, optical communications and neuromorphic engineering to examine the future of optical neuromorphic computing.

The workshop will cover specifically the following main topics:
1. Scaling of neuromorphic technology for high-performance signal processing
2. Applications for neuromorphic engineering

Efforts in enabling higher capacity tend to rely on constellation energy efficiency, multi-mode and multi-core fibres. But isn't it time to truly explore other transmission windows? For standard single mode fibre, work is emerging on the efficient use of S & O bands for short reach communications. Alternatively, hollow core fibres have the advantage of significant lower nonlinear interaction, benefiting for high power operation, and potentially shifting transmission to 2 µm.

This workshop aims to have a focus panel discussion that follows a series of short talks from stakeholders in industry and academia, with the aim to draft the challenges and needs to open these new transmission windows.

The next line rate for PON has been agreed in the ITU as 50G. This is a considerable increase on the previous highest ITU PON line rate of 10G as seen in XG(S)-PON and NG-PON2. Now that 10G line-rate PON is taking off in the market, with many large deployments underway and planned, it is time to define the next evolution step. Key issues to understand include the application drivers and the most relevant technologies to achieve 50G+ at the low costs usually expected in access applications.

With speakers from across the value chain, this workshop will aim to address the requirements/applications for higher capacity in PON and the possible technological choices for the system and underlying components. We will learn whether the main applications are still residential or whether 5G and business/backhaul services will be important. What requirements will network operators have for co-existence with legacy PON and operation over already deployed infrastructure? Are there any new requirements beyond the higher capacity?

Concerning the system aspects, will more advanced modulation formats beyond NRZ become useful and is there a role for DSP or coherent reception? How can the challenging PON loss budgets of today be handled without adding significant complexity and/or cost? Will the required optical components be available and what about the challenges of burst-mode electronics at such high speeds?
