Abstract
A method is provided for fabricating composite nonlinear optical (NLO) organic films that are suited for use in NLO device applications. The highly NLO properties of these films arise from the vector alignment of `guest` NLO molecules in a self-ordered nano-structured liquid crystal `host` film. Field-poling is used to remove the centro-symmetry. The `guest` concentration is increased by film processing to incorporate oriented nonlinear nano-crystallites to increase nonlinearity. NLO devices based on such films are of low cost and permit fast switching in a compact device format.
