Abstract

Different dielectric thin films are being studied in order to facilitate the processing of low loss multiple metallic dielectric hollow glass waveguides (HGWs). In this paper, we present our results for high index lead sulfide (PbS) and low index optical polymers, especially, polystyrene (PS) and cyclic olefin polymer (COP). We have observed that the morphology of the thin film is dependent on the processing conditions. The morphology of the metal and dielectric thin film affects the attenuation of the hollow glass waveguides. We have been successful in depositing and controlling the morphology of high n PbS thin films and low n polymer films. In order to aid in thin film characterization we have also deposited on planar substrates.
