2018 | O’COMEX : Optical Communications in Comex

Axe : comEx
Coordinateurs : Catherine Lepers, Elie Awwad
Financement Labex : 2017-2021


Présentation : Ce GT se situe dans la tâche “Communications Optiques” de l’axe Comex du Labex. La thématique de ce GT est de se préoccuper des problématiques réseaux optiques fibrées courte et longue distance ainsi que des problématiques des systèmes de communication optique sans fils. Les plus importantes directions de recherche du GT s’articulent autour du :

  • Traitement des effets non-linéaires dans la fibre
  • Traitement des schémas multi-voies (systèmes WDM, fibres multi-cœurs, multi-modes)
  • Optimisation des réseaux optiques notamment sa consommation énergétique et sa capacité de se reconfigurer et se rétablir suite aux anomalies.
  • Codage pour les systèmes optiques
  • Apprentissage automatique appliqué aux systèmes de communication

Équipes concernées :

  • LSS : Antoine Berthet, Zeno Toffano
  • LTCI : Elie Awwad, Philippe Ciblat, Yves Jaouën, Ghaya Rekaya, Mansoor Yousefi, Cédric Ware

    • Project Summary: the future of Internet depends on meeting ever-increasing capacity needs while curbing the energy consumption’s uncontrolled growth in data networks and reducing the end-to-end latency of mobile networks. Optical functionalities (OFs), such as wavelength conversion, all-optical regeneration and optical packet switching, have a tremendous potential to solve these challenges by reducing the required number of optical-to-electronic (O-E) conversions and leveraging the lower energy cost per bit of optical transmissions. Unfortunately, such OFs that ought to be “killer applications” have never gained any significant market share, because they don’t easily fit the conventional layered network model. Our team is currently working on new ways to handle OFs, moving towards making smarter networks aware of these OFs’ advantages and drawbacks, leveraging the concepts currently being pushed by software-defined networking. A prerequisite to this is a reliable assessment of the physical impairments incurred by these functionalities and their consequences at a system level (bit error rate, spectral broadening…) We have developed a synthetic model of physical impairments of optical networks, which we integrated into a network simulator that lets us evaluate the possible benefits of OFs such as wavelength conversion.
