Photoresponsive Polymer Films for Photo-Patterned Waveguides

University of Arizona researchers have developed a new class of high refractive index polymers that can be deposited as thin films and directly photo-patterned into useful device architectures. The resulting cured (e.g. photo-exposed) regions have a reduced refractive index, which is 0.01-0.05 lower than the unexposed regions and, hence, have tremendous...
