Abstract

Diffraction gratings, waveguides, and resonators are components of photonic devices that can be fabricated using chalcogenide glasses. These chalcogenide components can be made through a process of direct laser writing and etching to reveal targeted structures on the surface of the films. Thermal deposition in combination with targeted laser irradiation has been used on As2S3 films with excellent results, but spin-coating as a method of deposition has been less explored. Spin-Coating is a relatively inexpensive procedure where a bulk glass is dissolved into a solution using amines and “spun” onto a substrate. This is a low-cost alternative for film deposition that can be combined with lithography techniques for photonic device fabrication. This paper outlines spin coating and characterization of films on a substrate for the purpose of direct laser writing.
