ABSTRACT:
Optical systems and methods for optical wavelength conversion are provided. One such exemplary optical system includes a waveguide located in a substrate at least partially of a non-linear optical material, the waveguide structured to receive a continuous-wave optical signal. Also included is a grating located at least partially in the non-linear optical material section of the waveguide. The grating has a period “d,” and the waveguide produces a photonic bandgap when a forward propagating state of photonic energy of the continuous wave signal is separated from a backward propagating state of photonic energy of the continuous wave optical signal by a wavenumber (kz) equal to (2π/d), at a first photonic energy level in the waveguide.
