Abstract

Efficient transmission of light through a matrix isolation thin film is obtained despite the fact that the index configuration of the thin film is not appropriate for classical waveguides. The light is transmitted through the film approximately parallel to the substrate, thereby permitting analysis of the thin film, stimulation of reaction within the thin film, or use of the thin film as an optical memory.
