Abstract
We have prepared various polysilane copolymers that were functionalized wit h the nonlinear optical chromophore N-methyl-p-nitroaniline. The glass tran sition temperature of the polysilanes was adjusted to room temperature by c opolymerization of methylphenyldichlorosilane and n-hexylmethyldichlorosila ne. Asymmetric two-beam coupling was observed at 633 nm, and a gain coeffic ient of 18 cm(-1) was measured at an externally applied field of 48 V mu m( -1).
