Abstract
Since 2002, the THALES Group has been manufacturing sensitive arrays using QWIP technology based on GaAs and related III-V compounds, at the Alcatel-Thales-III-V Lab (formerly part of THALES Research and Technology Laboratory). In the past researchers claimed many advantages of QWIPs. Uniformity was one of these and has been the key parameter for the production to start. Another widely claimed advantage for QWIPs was the so-called band-gap engineering and versatility of the III-V processing allowing the custom design of quantum structures at various wavelengths in MWIR, LWIR and VLWIR. An overview of the available performances of QWIPs in the whole infrared spectrum is presented here. We also discuss about the under-development products such as dual band and polarimetric structures.
