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 distance detecting system for use in an automotive application comprises a gallium and nitrogen containing laser diode disposed within an automotive light. The gallium and nitrogen containing laser diode is configured to emit a first light with a first peak wavelength. A wavelength conversion member is configured to produce a white light. A first sensing light signal is based on the first peak wavelength. One or more optical elements are configured to direct at least partially the white light to illuminate one or more target objects or areas and to transmit respectively the first sensing light signal for sensing at least one remote point. A detector is configured to detect reflected signals of the first sensing light signal to determine coordinates of the at least one remote point.

Abstract: The present disclosure provides a distance detection system having at least a gallium and nitrogen containing laser diode and a wavelength conversion member. The gallium and nitrogen containing laser diode is configured to emit a first laser beam with a first peak wavelength. The wavelength conversion member is configured to receive at least partially the first laser beam with the first peak wavelength and reemit a second light with a second peak wavelength that is longer than the first peak wavelength and to generate the white light mixed with the second peak wavelength and the first peak wavelength. The distance detecting system further includes one or more first optical elements configured to transmit a first sensing light signal, and a detector configured to detect reflected signals of the first sensing light signal.

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.
