Efficient technique to calculate eigenenergies and eigenstates of arbitrarily shaped quantum wells and optimization of asymmetric quantum well optical switches

Abstract

We present a technique for calculating eigenenergies and eigenstates of arbitrarily shaped quantum wells in this paper. We compare the technique with some other conventional numerical method in the case of a rectangle quantum well and a step quantum well under an external electric field. The comparison shows that the technique is simple, time saving, but highly accurate. The technique is applied to the study of Stark shift, oscillator strength, and optical absorption on the conditions of variation of structure parameters and the strength of external electric field. We optimized structure for high performance asymmetric coupled quantum well optical switches.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
