New Photocrosslinking Polymers for Second Order Nonlinear Optical Processes

摘要

Polymeric systems have been established as useful materials for second ordernonlinear optical (NLO) processes, viz. frequency doubling, linear electro-optic effect, frequency mixing and parametric oscillation. Crosslinked systems are reported to exhibit stable second order properties. The system can be poled and photocrosslinked in the poled state to yield a material with stable optical
