    Abstract: In an example, the present invention provides an optical engine apparatus. The apparatus has a laser diode device, the laser diode device characterized by a wavelength ranging from 300 to 2000 nm or any variations thereof. In an example, the apparatus has a lens coupled to an output of the laser diode device and a scanning mirror device operably coupled to the laser diode device. In an example, the apparatus has an un-patterned phosphor plate coupled to the scanning mirror and configured with the laser device; and a spatial image formed on a portion of the un-patterned phosphor plate configured by a modulation of the laser and movement of the scanning mirror device.

    Abstract: A multi-wavelength light emitting device is manufactured by forming first and second epitaxial materials overlying first and second surface regions. The first and second epitaxial materials are patterned to form a plurality of first and second epitaxial dice. At least one of the first plurality of epitaxial dice and at least one of the second plurality of epitaxial dice are transferred from first and second substrates, respectively, to a carrier wafer by selectively etching a release region, separating from the substrate each of the epitaxial dice that are being transferred, and selectively bonding to the carrier wafer each of the epitaxial dice that are being transferred. The transferred first and second epitaxial dice are processed on the carrier wafer to form a plurality of light emitting devices capable of emitting at least a first wavelength and a second wavelength.

    Abstract: A laser illumination or dazzler device and method. More specifically, examples of the present invention provide laser illumination or dazzling devices power by one or more violet, blue, or green laser diodes characterized by a wavelength from about 390 nm to about 550 nm. In some examples the laser illumination or dazzling devices include a laser pumped phosphor wherein a laser beam with a first wavelength excites a phosphor member to emit electromagnetic at a second wavelength. In various examples, laser illumination or dazzling devices according to the present invention include polar, non-polar, or semi-polar laser diodes. In a specific example, a single laser illumination or dazzling device includes a plurality of violet, blue, or green laser diodes. There are other examples as well.

    Abstract: A plurality of dies includes a gallium and nitrogen containing substrate having a surface region and an epitaxial material formed overlying the surface region. The epitaxial material includes an n-type cladding region, an active region having at least one active layer overlying the n-type cladding region, and a p-type cladding region overlying the active region. The epitaxial material is patterned to form the plurality of dies on the surface region, the dies corresponding to a laser device. Each of the plurality of dies includes a release region composed of a material with a smaller bandgap than an adjacent epitaxial material. A lateral width of the release region is narrower than a lateral width of immediately adjacent layers above and below the release region to form undercut regions bounding each side of the release region. Each die also includes a passivation region extending along sidewalls of the active region.
