    Abstract: The present disclosure provides an apparatus for generating fiber delivered laser-induced white light. The apparatus includes a package case enclosing a board member with an electrical connector through a cover member and a laser module configured to the board member inside the package case. The laser module comprises a support member, at least one laser diode device configured to emit a laser light of a first wavelength, a set of optics to guide the laser light towards an output port. Additionally, the apparatus includes a fiber assembly configured to receive the laser light from the output port for further delivering to a light head member disposed in a remote destination. A phosphor material disposed in the light head member receives the laser light exited from the fiber assembly to induce a phosphor emission of a second wavelength for producing a white light emission substantially reflected therefrom for various applications.

    Abstract: A phosphor integrated laser-based light source includes a thermally conductive material arranged on a package base adjacent to a laser diode chip and an optically transparent material coupled to the thermally conductive material. A groove extends between the thermally conductive material and the optically transport material and is aligned to receive electromagnetic radiation from the laser diode chip. A wavelength conversion material is coupled to the optically transparent material and is configured to receive at least a portion of the electromagnetic radiation emitted into the groove and transmitted through the optically transparent material. A reflective material surrounds sides of the optically transparent material and the wavelength conversion material.

    Abstract: The present disclosure provides a method and structure for producing large area gallium and nitrogen engineered substrate members configured for the epitaxial growth of layer structures suitable for the fabrication of high performance semiconductor devices. In a specific embodiment the engineered substrates are used to manufacture gallium and nitrogen containing devices based on an epitaxial transfer process wherein as-grown epitaxial layers are transferred from the engineered substrate to a carrier wafer for processing. In a preferred embodiment, the gallium and nitrogen containing devices are laser diode devices operating in the 390 nm to 425 nm range, the 425 nm to 485 nm range, the 485 nm to 550 nm range, or greater than 550 nm.

    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.

    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.
