Diffusion, diffraction and reflection in semiconductor o.b. devices

Abstract
For reasons of speed and economy, applications of optical bistability are likely to concentrate on solid-state devices of small volume. In this paper we discuss the modelling and optimization of such devices. We report calculations of surface reflectivity optimization in the presence of absorption, and show that optical bistability in reflection offers significant advantages over transmission. Small transverse dimensions, i.e. dense packing, are limited by cross-talk between neighbouring devices. We show that diffraction and diffusion give rise to qualitatively similar effects
