Recent improvements of IRFPAs at LIR

This paper presents two types of recent focal plane arrays manufactured in Laboratoire Infrarouge (LIR) of CEA-LETI: (1) long linear arrays in the 12 micron wavelength range operating at 50 K consisting of several submodules butted together, and (2) 128 X 128 two dimensional arrays operating at 200 K with a 4.2 micron cutoff wavelength. Furthermore, basic studies have been carried out and an improvement of a factor of ten for the RoA value is now obtained on new homojunction MCT detectors. First results are presented here.
