Abstract
An illumination module may provide light in a plurality of colors including Red-Green-Blue (RGB) light and/or white light. The light from the illumination module may be directed to a 3LCD system, a Digital Light Processing (DLP®) system, a Liquid Crystal on Silicon (LCoS) system, or other micro-display or micro-projection systems. In one embodiment the illumination module includes a laser configured to produce an optical beam at a first wavelength, a planar lightwave circuit coupled to the laser and configured to guide the optical beam, and a waveguide optical frequency converter coupled to the planar lightwave circuit and configured to receive the optical beam at the first wavelength, convert the optical beam at the first wavelength into an output optical beam at a second wavelength, and may provide optically coupled feedback which is nonlinearly dependent on a power of the optical beam at the first wavelength to the laser.
