Optical Telecommunications [GTO]

The Optical Telecommunications Group (GTO) is home to the research programs of six faculty members and a state-of-the-art laboratory on optical fiber transmission. We conduct advanced research in high-rate fiber-optic transmission, optical network architectures, advanced lasers for communications, integrated photonics, and distributed optical fiber sensors.

GTO closely collaborates with the Digital Communications Group (ComNum) at Télécom Paris, as well as with world-renowned research groups in photonics and communications. These collaborations have led to the supervision of several joint doctoral theses and have made our position in inter-disciplinary research privileged and perhaps unique in France. Experimental demonstrations of novel concepts in optical communications is of strategic importance to GTO. Thanks to a state-of-the-art experimental platform, we have demonstrated high-speed transmission experiments using sophisticated modulation formats and DSP algorithms to compensate for various channel impairments.


The Optical Telecommunication Group (GTO) is particularly active in the following areas:

  • High-rate communications in short-reach and long-haul transmission systems
  • Optical networks architecture and cross-layer optimization
  • Performance improvement in optical devices and systems for context-driven applications
  • Quantum optics, non-linear photonics and laser dynamics
