ABSTRACT:
In one embodiment this invention provides a parametric frequency converting device which comprises a thin film of a polymeric medium which exhibits second order nonlinear optical response, and the device has heat control means for temperature tuning of the waveguide medium to phase match the propagation constants of fundamental and second harmonic light beams. In a preferred device the waveguiding medium has a spatial periodic structure for quasi-phase matching of the propagating wave energy, and optionally has a set of electrodes for application of a direct current electric field to the waveguiding medium.
