Paper Abstract

Crosslinked polymers offer the promise of great long term temporal stability and chemical resistance. However, a crosslinkable nonlinear optical (NLO) polymer is more difficult to be processed into high optical quality thin films than other type of NLO polymers such as side-chain, main-chain or guest-host polymers. The crosslinking process imposes more stringent requirements on the solvents. The process of searching for a compatible solvent for a crosslinkable NLO polymer is described. Two detrimental phenomena during the fabrication of electrooptic waveguides from crosslinkable polymers are reported. One is the crystallization of the crosslinker. The other is the formation of wavy surfaces when a commercially available optical adhesive is used to prepare the cladding. By anchoring the small molecules to the long chain NLO polymer and precuring the optical adhesive, good optical quality polymer waveguides are prepared.
