Paper Abstract

Quantum well infrared technology has been progressing rapidly in the last several years. There are a number of focal plane array development projects conducted in earnest around the world. Different applications areas are also being explored. In this article, I will give a brief overview of the current technology, and discuss some of our recent progresses. They include the more accurate prediction on the material optical properties, the better understanding of the light coupling mechanisms and the demonstration of the corrugated-QWIP FPAs. Despite the current achievements, there are still problems in QWIPs in reaching out to both low and high temperature operation. I will discuss the prospects of using quantum dots and quantum grids in improving this technology.
