Synthesis of crosslinkable fluorinated linear-hyperbranched copolyimides for optical waveguide devices

Fluorinated photopolymer waveguide thermo-optic switches with loss-compensation function based on erbium-containing cladding structure

Thermo-optic switches with loss-compensation are achieved using FBPA-PC EP and GETPM. The multi-functional device is appropriate for opti-electronic integrated circuits.

Novel soluble poly(ether imide)s with trifluoromethyl and chloride pendant groups for optical materials

A series of novel PEIs (4a–4e) with ether linkages and bulk side groups in the backbone have been successfully synthesized. It was very interesting that they also had excellent optical properties.
