Abstract: A system, a structure, and a method for the generation of second harmonic light are provided. A laser system comprises a seed laser that produces a fundamental frequency light, and a nonresonant multiple pass nonlinear structure generates a second harmonic light using the fundamental frequency light. A second harmonic outcoupler outputs the second harmonic light from the laser system and a reflecting structure reflects a remaining portion of the fundamental frequency light back into the nonresonant multiple pass nonlinear structure to generate additional second harmonic light.

Abstract: A waveguide to waveguide coupled hybrid master oscillator power amplifier (MOPA) includes a wavelength locked laser master oscillator (MO) first chip including a semiconductor substrate, a waveguide region having a gain section, one side of the MO including an integrated wavelength selective feedback element and the other side of the MO including an integrated reflective or coupling element on one side the waveguide and an emitting surface opposite the integrated reflective or coupling element for emitting light. A power amplifier (PA) second chip is stacked above or below the MO. The PA includes a semiconductor substrate including a waveguide region having a gain section, an integrated reflective or coupling element on a side of the PA aligned with light emitted from the emitting surface of the MO and a coupling grating or turning mirror and integrated lens on an opposite side of the PA for emitting an output beam.

Abstract: An integrated light emitting semiconductor device having integrated feedback for wavelength locking comprises a semiconductor substrate including a waveguide region having a gain section having a gain media therein, and an out-coupling perturbation integrated with the device disposed proximate to the waveguide. A total internal reflection (TIR) structure for providing optical feedback is integrated with the device and disposed in a spaced apart relation relative to the out-coupling perturbation. At least one of the out-coupling perturbation and the TIR structure include a grating or prism to provide dispersion to send different wavelengths of light in different directions. The out-coupling perturbation is preferably a grating that has a grating period that is small enough to allow for only the +1 diffracted order to propagate.
