Abstract

Optical memories consisting of arrays of bistable pixels are considered. Attainable pixel density is limited by cross-talk, so that there is a minimum pixel separation for which all pixels may be independently held "on" or "off". This problem is analysed for diffusive cross-talk between members of a linear array of pixels. A nonlinear dynamics analogy links pixel independence to spatial chaos, and enables estimates of minimum pixel density. The stability of pixel patterns is governed by a form of Schrodinger equation. More realistic models should show similar features.
