Abstract
In one embodiment this invention provides a frequency doubling optical waveguide consisting of a substrate-supported polymeric thin film waveguiding layer, in combination with one or more polymeric cladding layers. The waveguiding layer comprises moieties which exhibit nonlinear optical properties as well as anomalous dispersion of refractive index such that, under wave propagating conditions, the effective dispersion .DELTA.N of the waveguiding layer is zero, and the fundamental and second harmonic waves are phase matched over the length of the waveguide.
