QWIP Performance and Polarization Selection Rule

  title={QWIP Performance and Polarization Selection Rule},
  author={H. C. Liu and Matt Buchanan and Zbigniew R. Wasilewski},
In this paper, we address two separate topics related to quantum well infrared photodetectors (QWIPs). First, we discuss the key parameters that determine the performance of QWIP, and point to the direction for future work to improve the performance. Analytical expressions for detectivity and background limited operating temperature are given. This enables a easy identification of key parameters and their relations to the performance characteristics. Second, using GaAs based QWIPs with either… CONTINUE READING
