Abstract: A structured phosphor device includes a frame member that includes wall regions separating multiple openings of window regions. Further, the structured phosphor device includes a phosphor material filled in each of the multiple openings with a first surface thereof being exposed to an excitation light from one or more laser sources to generate an emitted light out of each window region. Additionally, the structured phosphor device includes an anti-reflective film overlying the first surface of the phosphor material. Furthermore, the structured phosphor device includes a substrate attached to a second surface of the phosphor material in each of the multiple openings. Alternatively, the structured phosphor device includes an array of phosphor pixels dividing a plate of single-crystalline or poly-crystalline phosphor material separated by optically reflective and thermally conductive walls. A dynamic lighting system based on the arrays of phosphor pixels for single or full color image projection is also disclosed.

Abstract: A method for manufacturing a laser diode device includes providing a substrate having a surface region and forming epitaxial material overlying the surface region, the epitaxial material comprising an n-type cladding region, an active region comprising at least one active layer overlying the n-type cladding region, and a p-type cladding region overlying the active layer region. The epitaxial material is patterned to form a plurality of dice, each of the dice corresponding to at least one laser device, characterized by a first pitch between a pair of dice, the first pitch being less than a design width. Each of the plurality of dice are transferred to a carrier wafer such that each pair of dice is configured with a second pitch between each pair of dice, the second pitch being larger than the first pitch.

Abstract: A light source system or apparatus configured with an infrared illumination source includes a gallium and nitrogen containing laser diode based white light source. The light source system includes a first pathway configured to direct directional electromagnetic radiation from the gallium and nitrogen containing laser diode to a first wavelength converter and to output a white light emission. In some embodiments infrared emitting laser diodes are included to generate the infrared illumination. In some embodiments infrared emitting wavelength converter members are included to generate the infrared illumination. In some embodiments a second wavelength converter is optically excited by a UV or blue emitting gallium and nitrogen containing laser diode, a laser diode operating in the long wavelength visible spectrum such as a green laser diode or a red laser diode, by a near infrared emitting laser diode, by the white light emission produced by the first wavelength converter, or by some combination thereof. A beam shaper may be configured to direct the white light emission and an infrared emission for illuminating a target of interest and transmitting a data signal. In some configurations, sensors and feedback loops are included.

Abstract: A laser-based fiber-coupled white light system is provided. The system includes a laser device comprising a gallium and nitrogen containing emitting region having an output facet configured to output a laser emission with a first wavelength ranging from 385 nm to 495 nm. The system further includes a phosphor member integrated with light collimation elements. The phosphor member converts the laser emission with the first wavelength to a phosphor emission with a second wavelength in either reflective or transmissive mode and mixed partially with laser emission to produce a white light emission. The system includes a transport fiber coupled to the phosphor member via the light collimation elements to receive the white light emission and deliver the white light emission remotely to one or more passive luminaries substantially free of electrical or moving parts disposed at remote distances from a dedicated source area.
