MODELLING OF CROSS TALK IN 2D BISTABLE ARRAYS AND NOISE ON AN InSb ETALON

Abstract
We present a theoretical model based on the diffusion equation for the single-pass nonlinear phase shift and apply it to an InSb etalon irradiated by a two-dimensional array of beams. Independent operation of the individual elements depends on a critical spacing which we determine as a function of the holding power. When the plane-wave limit of our model is taken, the resulting equation can be likened to that of an overdamped particle subject to a conservative force. This enables us to describe a mechanism for noise-induced transitions.
