In one embodiment this invention provides a frequency doubling optical waveguide consisting of a substrate-supported polymeric thin film which exhibits second order nonlinear optical response and is thickness variation insensitive, and which has a periodic structure for quasi-phase matching of propagating laser wave radiation. In a preferred embodiment the waveguide has a two-dimensional channel structure for intensified single mode wave transmission.
