Abstract

All-optical poling of a series of side-chain azobenzene copolymers with different azo content and homopolymer was experimentally investigated. The maximum photoinduced SHG was observed when the weight percent of azo in copolymer attained to about 60%. The photoinduced SHG decay process show that copolymers and homopolymer all have higher temporal stability than typical guest-host DR1-PMMA system; moreover, no obvious difference was observed between copolymers and homopolymer. The results indicated that optimal NLO copolymer could be obtained by controlling the azo content of molecule structure in all optical poling..
