Abstract

We have designed and fabricated GaAs/AlGaAs QWIP photodetector for THz range of spectrum (3THz, 100 μm). To evaluate suitability of this type of detector for real-time THz imaging, a prototype of a small array have been built by integrating detector elements with cryogenic readout electronics. Up to 32 individual channels can be measured with this system at temperatures down to 4K. In this paper we present the design and expected performance of GaAs/AlGaAs THz QWIP integrated with cryogenic readout electronics (CRE), and discuss key development issues related to the design.
