Abstract
The development of quantum well infrared photodetector (QWIP) technologies for thermal imaging is well known. The high frequency and high speed capability is less known. Here we report on our recent advances of reaching over 100 GHz in heterodyne detection both at cryogenic and room temperatures. These advances may lead to new applications. One of such examples is free space optical communication.
