Comparative study of photobleachable polysilane copolymers applied to optical waveguides

► In this work, three different PMPS based copolymers, PMPS-PMMA, PMPS-poly(styrene) (PS), and PMPS-PBzMA were synthesized. ► As photobleachable polymers for waveguide fabrication, their UV spectra, photobleaching, refractive index change and optical properties were comparatively studied. ► Channel waveguides were fabricated using these copolymers and their optical propagation properties were investigated.
