Abstract: An optical parametric oscillator (OPO) including a thin film waveguide including a material having a second order nonlinear susceptibility generating an electromagnetic field in response to pump electromagnetic field inputted into the thin film waveguide. The electromagnetic field has a first wavelength or first set of wavelengths longer than a second wavelength or second set of wavelengths of the pump electromagnetic field. The thin film waveguide has a thickness on the order of the first wavelength or the first set of wavelengths in the thin film waveguide so as to guide the electromagnetic field along the thin film waveguide.
