We will discuss our recent efforts on the synthesis of a new class of Chalcogenide Hybrid Inorganic/Organic Polymers (CHIPs) that exhibit photo-definable refractive index with high spatial control using photolithographic methods. We report on a the synthesis of new styrenic sulfide monomer that can be readily polymerized via controlled radical polymerization methods to afford well-defined homopolymers and copolymers of precise molar mass and composition. Solution processing of these polymers with photoacid generators into thin films, followed by photoirradiation enables a sharp and tunable change in refractive index in the photo-exposed regions. Photopatterning of this polymeric material affords a facile approach for the fabrication of polymeric optical devices, such as, waveguides and optical interconnects with very high refractive index contrast.
