Abstract

A novel technique for fabrication of thin-film gratings is reported. A CdS film, deposited onto an ion-exchanged glass waveguide, is photo-etched by a focussed Ar-laser beam. Computer-controlled movement of the sample allows for the formation of periodic structures, tested for input and output coupling. Some interesting effects due to the simultaneous presence of longitudinal and transverse gratings are discussed. We also propose the technique in the realization of integrated optical devices for communications.
