Abstract

We have recently shown that by the use of a 'lock and clock' architecture and an off-axis configuration of the power and signal beams indefinitely extensible optical logic is possible. The demonstration optical circuits which have been constructed use optical logic gates based on nonlinear interference filters (NLIF). These NLIF operate over a range of wavelengths extending throughout the visible to the NIR. This large range is due to the origin of the nonlinearity which is a thermally-induced change in refractive index. 3 refs.
