Photoprocessable Second Order Nonlinear Optical Polymers

Abstract

Dye-doped polymers and polymers with covalently attached nonlinear-optical (NLO) moieties have demonstrated that large second-order susceptibilities in polymers are achievable. For practical applications, the stability of Chi(2) at elevated temperatures and the ease of processing into guided wave structures are equally important and need to be addressed. Recently, it has been reported that thermally crosslinked epoxy polymers are stable at temperatures above 100 deg C. Thermally crosslinked NLO polymers, however, require several hours of high temperature curing under a high electric field. This often leads to deterioration of the optical quality of the films. An alternative route to obtain stable, crosslinked electro-optic polymers by photochemical crosslinking has been developed in our laboratory.
