Paper Abstract

The major drawback of IR photodetectors is the need for cooling to suppress thermal generation of free carriers resulting in noise. New ways to improve the performance of infrared photodetectors operated without cryogenical cooling are discussed including the optimum design of the devices, the use of optical immersion of photodetectors to high refraction index lenses and optical resonant cavity. Another and very promising way, however, is the suppression of thermal generation which is governed by Auger mechanism by depletion of semiconductor in charge carriers. The combination of various methods would eventually enable achievement near-BLIP performance of IR detectors without cooling.
