  • Patent number: 10599007
    Abstract: Various embodiments of the present technology provide a novel architecture for optical frequency conversion in a waveguide which can be applied to any suitable nonlinear waveguide material and any wavelength. In accordance with some embodiments, phase-matched bends can be used to increase the nonlinear interaction length. For example, the device can begin with a straight waveguide section with a width designed for phase-matching. When the straight waveguide section approaches the end of the chip, a bending waveguide section allows the waveguide to meander back in the opposite direction. Various embodiments of the bend can have a wider or narrower width to eliminate phase-matching for second harmonic generation (SHG) and instead provide a 2? phase-shift between the pump and signal light. Therefore, at the end of the bend, the pump and signal light are in-phase and a phase-matched width will continue the SHG process.
