Modal propagation within MQW waveguides

Abstract

The propagation of TE modes and TM modes within planar multiquantum waveguides with large numbers of wells and barriers is shown to exhibit markedly different behavior for the two polarization states. The solutions for these two modes are developed for an arbitrary number of N barriers, and zero- and first-order approximations in powers of 1/N are calculated for quantities of physical interest. A very high geometric birefringence is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
