Polymeric Waveguide Materials for Integrated Optics

3 and 1.55 pm are located in the windows, absorption owing to C-H bonds increases die optical losses at these wavelengths. 

Polyimides and epoxy resins have been investigated as optical waveguide materials because they have excellent thermal, chemical, and mechanical stabi-The first attempt to use polyimide for optical waveguides was made by
