Coherent Optics for Short Reach Network (CSN)

Photonic communication networks seek for novel and disruptive concepts that boost their capacity and efficiency. As an enabler for such, coherent communications exploits the best quiver of opto-electronic component technology, analogue or digital signal processing, and novel receiver architectures in order to beat legacy direct-detection solutions. Under the umbrella of this evolution, coherent technology is evading shorter and shorter links and finds itself in an environment where stringent requirements in terms of cost and energy apply.

The topic of coherent optical communication seeks contributions for short-reach applications and includes, but is not necessarily limited to:

  • Opto-electronic devices for coherent data transmission
  • Novel concepts for coherent reception
  • Novel schemes for efficient higher-order modulation
  • Analogue signal processing
  • Hardware-efficient digital signal processing
  • Coherent optical interconnects and intra-datacenter networks
  • Coherent access networks and wireless x-haul
  • Quantum communications
  • Cost/energy performance analyses for coherent network applications
  • Novel network architectures leveraging coherent technologies
  • Performance trials in lab and field

Signal Reconstruction Using Photonics (SR)

This topic focuses on photonic-enhanced signal reconstruction and photonic-assisted information processing.
It wants to gather researchers working on different technological levels from theory, component to implementation and across different applications together to learn state of the art, exchange ideas and inspire potential collaborations across different disciplines.
Following fields will be covered in the topic:

  • Ultrashort pulses analysis and broadband signal characterization in temporal, spectral, and spatial domains;
  • Photonic time stretching techniques for wideband signal acquisition;
  • Photonic-enhanced compressed sensing;
  • Photonic and opto-electronic reservoir computing;
  • Photonic-based supervised and unsupervised learning for image classification;
  • Phase retrieval methods such as self-referencing, optical alternative projection and optical random projection;
  • Kramers–Kronig relations and optical full field reconstruction for communication;
  • Integrated photonics for combinatorial optimization problems;
  • Remote sensing and ghost imaging;
  • Image recovery after scattering medium;
  • Quantum signal processing and computing

Silicon Integrated Mid-Infrared Photonics (SIMP)

SIMP topical meeting aims at bringing together photonics engineers, material scientists, physicists and technology experts to present and discuss the recent developments in mid-IR integrated photonics and to evaluate their potential impact on future application needs. The symposium is also an active platform to highlight and discuss the latest progress in the emerging area of (Si)GeSn semiconductors including fundamental studies of their basic properties as well as new device designs for their integration in silicon-compatible mid-infrared photonics and optoelectronics.

Space Division Multiplexing (SDM)

Space division multiplexing (SDM) in multi-mode and multi-core fibers has been a major topic in optical communications since the beginning of the present decade. SDM research aims at exploiting spatial diversity in optical transceivers, fibers, amplifiers, routers etc. to increase the per-link transmission capacity while reducing cost, complexity, and eventually energy consumption. Research on SDM has been fueled worldwide by numerous multi-national research projects in the USA, Europe, Japan and China, and is further making its way towards field deployment, e.g. in a recently announced submarine cable installment, where SDM amplification solutions have been employed, while standardization of certain SDM fibers is now actively discussed with a strong industry interest.

This topic intends to gather the key players in SDM research from around the world to establish an overview of the state of the art of current research regarding devices, fibers and systems. Secondly, we aim to stimulate an open discussion on the challenges and opportunities envisaged in the devising of massive parallel transmission systems that are necessary in response to the ever-increasing demand for data traffic. Finally, we plan to explore applications of SDM technologies and devices in optics-related research areas that are not necessarily connected to fiber-optic communications.

The meeting will focus on the following topics:

  • Progress in SDM transmission and SDM fiber design.
  • Progress in integration of transceivers, amplifiers, switches, mux/demux, and other components for SDM.
  • Initial investigations of field-deployed SDM fibers with focus on the INCIPICT project in L’Aquila.
  • Propagation modelling and fundamental limits of various SDM fibers: cross-talk and random-mode coupling, modal dispersion, mode-dependent loss, nonlinear effects, interplay between various effects, time dynamics.
  • Progress in digital signal processing for SDM fibers
  • Using SDM technologies in “non-conventional” SDM applications: Quantum communications, signal processing / RF fronthaul / 5G / satellite communications / astronomy and endoscopy.

Structure Light Interaction with Matter and the Environment (SL)

In this topic we will bring together a broad spectrum of researchers from many different disciplines that investigate and utilise the interactions of various forms of structured and shaped optical fields with material and the environment. We wish to engage with researchers that are not typically within the same community to discuss their research and inspire new cross-disciplinary collaborations.

Research talks will be from across the themes:

  • Optical control and characterization technologies for structured light
  • Optical matter interactions with structured light
  • Scattering medium, complex media, and metasurfaces
  • Orbital Angular Momentum
  • Spin-orbit interactions with materials
  • Remote sensing of air, marine or space environments
  • Quantum and classical sensing
  • DSP technologies for information retrieval from structured light
  • Waveguides and fibers supporting structured/multimode light
  • Non-linear interactions in novel optical fibers, waveguides, and materials
  • SBS and other acoustic-optical effects
  • Multimode fibre amplifiers and novel gain media for structured light

We invite leading researchers from industry, government research facilities and academia to contribute to the conference and we envisage this conference will act to accelerate the progress of this emerging hot topic in photonics.
