    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 to receive the laser emission in a range of angles of incidence to a spot on a primary surface with a size greater than 5 μm. 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 at least partially with laser emission to produce a white light emission. Additionally, the system includes a fiber coupled to the phosphor member to capture the white light emission to deliver the white light emission to a remote lighthead or distribute the white light emission directly.

    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.

    Abstract: A method for fabricating a laser diode device includes providing a gallium and nitrogen containing substrate member comprising a surface region, a release material overlying the surface region, an n-type gallium and nitrogen containing material; an active region overlying the n-type gallium and nitrogen containing material, a p-type gallium and nitrogen containing material; and a first transparent conductive oxide material overlying the p-type gallium and nitrogen containing material, and an interface region overlying the first transparent conductive oxide material. The method includes bonding the interface region to a handle substrate and subjecting the release material to an energy source to initiate release of the gallium and nitrogen containing substrate member.

    Abstract: A smart light source configured for visible light communication. The light source includes a controller comprising a modem configured to receive a data signal and generate a driving current and a modulation signal based on the data signal. Additionally, the light source includes a light emitter configured as a pump-light device to receive the driving current for producing a directional electromagnetic radiation with a first peak wavelength in the ultra-violet or blue wavelength regime modulated to carry the data signal using the modulation signal. Further, the light source includes a pathway configured to direct the directional electromagnetic radiation and a wavelength converter optically coupled to the pathway to receive the directional electromagnetic radiation and to output a white-color spectrum. Furthermore, the light source includes a beam shaper configured to direct the white-color spectrum for illuminating a target of interest and transmitting the data signal.
