    Abstract: The present disclosure provides an apparatus for generating fiber delivered laser-induced dynamically controlled white light emission. The apparatus includes a laser diode unit for generating a laser electromagnetic radiation with a blue emission in a range from 395 nm to 490 nm that is delivered by an optical fiber. The apparatus further includes a dynamic phosphor unit configured to receive the laser exited from the optical fiber and controllably deflect a beam focused by a first optics sub-unit to a surface spot on a phosphor plate to produce a white light emission. Additionally, and the dynamic phosphor unit includes a second optics sub-unit configured to collect the white light emission and to project to a far field. Furthermore, the apparatus includes an electronics control unit comprising a laser diode driver and a MEMS driver for respectively control the laser diode unit and the dynamic phosphor unit in mutually synchronized manner.

    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.
