Abstract
We report on the design and characterization of methylmethacrylate copolymers with nonlinear optical 4-alkoxy-4'-alkylsulfone stilbene sidechains, which are transparent down to 410 nm. A fairly stable, polar orientation has been obtained by means of electric field poling, resulting in a reasonably high nonlinearity (d33 square; 9 pm/V). Phase matched second harmonic generation in planar waveguides of these polymers is achieved by means of spatially periodic photochemical bleaching of the stilbene sidechain.Keywords
