Simulation of performance of quantum well infrared photocetectors

In this thesis the performance of a step quantum well infrared photodetector, designed by Kevin Lantz (June 2002) and experimentally studied by Michael Touse (September 2003) and Yeo Hwee Tiong (December 2004), was simulated in Matlab using the transfer matrix method. The results obtained by the Matlab program are compared with the experimental results in a try to make inferences about the optimum way of designing QWIP detectors. Simulation of the above implies numerical solution of the SchroÌ dinger equation, using algorithms and methods, which give accurate results. In our approach, the transfer matrix method is used with exponential and, Airy functions to represent the solutions to SchroÌ dinger equation under zero and nonzero bias, respectively. In the final section of the thesis we examine and simulate in Matlab the application of the extended Kalman filtering (EKF) to an infrared photodetector as a target tracking mechanism to both maneuvering and non-maneuvering targets.
