Light source utilizing a light emitting device constructed on the surface of a substrate and light conversion device that includes a portion of the substrate |
摘要 |
A light source constructed from a light emitting device and a light conversion device. The light-emitting device emits light of a first wavelength and includes a semiconductor device on a surface of a substrate. The light conversion device includes a portion of the substrate. The light conversion device receives the light of the first wavelength and emits light of a second wavelength different from the first wavelength. The substrate includes a crystal of a fluorescent material doped with an activator. The light emitting device is preferably a light emitting diode or a laser diode. In one embodiment of the invention, the light emitting device is constructed in a groove in the substrate such that light generated by the light emitting device enters the wall of the groove. Embodiments of the invention for generating second-harmonic light may be constructed by including a waveguide structure in the substrate and alternating polarized regions formed in the substrate perpendicular to the light propagation direction
