1 May 1994Recent progress on GaAs quantum well intersubband infrared photodetectors
The current status of GaAs quantum well intersubband infrared photodetectors are presented by briefly reviewing some examples of the detector structures and their characteristics. The uniqueness of this new approach to infrared detection is painted out by presenting the multicolor and high-speed capabilities.
