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 a lighthead for either directly distributing white light on road or to a leaky fiber for illumination applications by side-scattering.

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.
