At ISAE SUPAERO, the Department of Electronics, Optronics and Signal Processing (DEOS) develops skills in signal processing, information processing, and data analysis.

The «Photonics Antenna Microwave PlasmA » group aims to study the applications of the electromagnetism to the Microwaves and Photonics and their interactions with plasma.

Optoelectronics for payloads and aerospace telecommunications

The OPTO theme of the PAMPA group aims to increase and secure the information transmission rate through optoelectronic links, integrate and qualify active components (semiconductor lasers, optical amplifiers, photo-detectors) in spatial payloads and aeronautics .

Microwave-Photonics and Photonic devices

The design of microwave-photonic systems requires a deep knowledge of the physics of photonic devices in order to develop models adapted to the different operating modes (static, dynamic, noise). These models are validated experimentally using experimental benches dedicated to different devices and adapted to a wide frequency range (up to 65GHz).

The team then designs systems for the generation of microwave or digital signals for the time and frequency reference. More specifically, OPTO designs Optoelectronic Oscillators and frequency combs based on VCSEL (Vertical cavity surface emitting laser).

While fiber optic telecommunications allowed the deployment of the Internet between continents and optimized the use of wired terrestrial links, the increase of mobile devices requires a considerable bandwidth growth of space and wireless communications. The free space approach then makes it possible to overcome the limitations of the radio frequency band. The team then studies, in partnership with IRT Saint Exupéry, CNES and AID, satellite-to-ground laser links.

OPTO lead its research at different levels:

  • Optical terminals and communication chain
    - OPTO with IRT Saint-Exupery participated to the design of the test bench dedicated dot le end-to-end satellite ground laser link (ELLA - Emulation de lien Laser Satellite Sol)
    - OPTO achieve a test bench for the emulation of the effect of the atmospheric turbulences on the wavefront of the laser beam.
