    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 method for manufacturing a multi-emitter 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 multi-emitter laser diode device includes a carrier chip singulated from a carrier wafer. The carrier chip has a length and a width, and the width defines a first pitch. The device also includes a plurality of epitaxial mesa dice regions transferred to the carrier chip from a substrate and attached to the carrier chip at a bond region. Each of the epitaxial mesa dice regions is arranged on the carrier chip in a substantially parallel configuration and positioned at a second pitch defining the distance between adjacent epitaxial mesa dice regions. Each of the plurality of epitaxial mesa dice regions includes epitaxial material, which includes an n-type cladding region, an active region having at least one active layer region, and a p-type cladding region. The device also includes one or more laser diode stripe regions, each of which has a pair of facets forming a cavity region.
