ABSTRACT:
A switch matrix which comprises non-linear optical (e.g. bistable) elements each consisting of an optically active layer applied to a substrate. The surface of the substrate has a microstructure composed of pillars each of which functions as a switch element and has at least one optically active layer. The pillar structure prevents interaction due to thermal contact and diffusion of charge carriers across the optically active layer and the substrate. The lithographic-galvanic (LIGA) process described is suited to the mass production of these structured substrates my moulding plastics. Both transparent and opaque substrates with high aspect ratios and adequate stability can be advantageously manufactured in this way.
