Third-Order Optical Nonlinearities in a Photocrosslinkable Polymer

摘要

Quadratic electro-optic coefficient measurements on a dye dopedphotocrosslinkable nonlinear optical (NLO) polymer-PVCN (polyvinylcinnamate)/CNNB-R (3-cinnamoyloxy-4-4-(N,N-diethylamino)-2cinnamoyloxy phenylazo nitrobenzene) at different dye concentrations are reported. No phase segregation was observed for dye concentrations up to 67 wt% in this polymer system. Large quadratic electro-optic coefficients were measured at 633 nm with a Michelson interferometer.
