Abstract:We are developing corrugated quantum well infrared photodetector (C-QWIP) technology for long wavelength applications. A number of large format 1024 × 1024 C-QWIP focal plane arrays (FPAs) have been demonstrated. The measured quantum efficiency η is ranging from 15 -37%, depending on the detector type, doping density and number of quantum wells in the detector material. The photoconductive gain is between 0.07 and 0.19, while the spectral width is between 1.5 and 3.5 microns. Despite the large integrated η of … Show more
