Infrared/Teraherz Detectors & Imagers
Research Team

The Group of Electrical Engineering - Paris (GeePs), created on the 1st January 2015 is a CentraleSupélec lab recognized by CNRS (UMR 8507), Sorbonne Université and Université Paris-Saclay. Our research activity is developed within the Materials department, through various topics (Nano-Materials, Devices and Characterization; Sensors and Functional Materials; Waves and Propagation).

​

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 :

​

1. Elaboration and characterization of thin films of oxides (semiconductors, superconductors).

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

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

• Active imaging, with uncooled semiconductor pixels, working in direct detection.

• Passive imaging, with cooled highly sensitive pixels of the superconducting hot electron bolometer (HEB) heterodyne mixer type.
