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
