The Paris Electrical Engineering Laboratory (LGEP-Supélec) became the Group of Electrical Engineering - Paris (GeePs) on the 1st January 2015. It is a CentraleSupélec laboratory recognized by CNRS (UMR 8507), UPMC Sorbonne Universités and Université Paris-Sud (Université Paris-Saclay).

We develop our research activity within the Physics and Engineering of Electromagnetism department (PIEM department).

What do we do?

We develop innovative materials and devices for photonics. A strong point to mention here is the complete mastering of the whole “materials - devices - system” chain :

i) Elaboration and characterization of thin films of oxides (superconductors or semiconductors).

ii) Development of thermal detectors (bolometers, pyroelectric detectors) for the near and mid-infrared and the terahertz range (500 GHz to 10 THz).

iii) Infrared and THz imaging systems; design and test. Two types of imaging systems are investigated:

• Passive imaging, with cooled highly sensitive pixels of the superconducting hot electron bolometer (HEB) heterodyne mixer type.
  
• Active imaging, with uncooled semiconductor pixels, working in direct detection.
