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.

Manufacturable multi-emitter laser diode

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.
