Abstract
A laser diode array includes a plurality of discrete emitter sections mounted on a substrate. Each discrete emitter section includes a light emitting material having an active region and an inactive region. The substrate provides electrical isolation between adjacent discrete emitter sections. A plurality of wire bonds electrically connects the plurality of discrete emitter sections in a series configuration.

A method of forming a laser diode array, comprising:
- mounting a light emitting material having an active region and an inactive region on a substrate;
- removing one or more portions of the inactive region and one or more portions of the substrate to form a plurality of discrete emitter sections in the light emitting material, each discrete emitter section electrically isolated from an adjacent discrete emitter section;
- and
- electrically connecting the plurality of discrete emitter sections in a series configuration to form the laser diode array.

A method of preventing indium migration in a series connected, continuous wave laser diode array, comprising:
- providing a light emitting material having a plurality of active regions spaced on a surface of a substrate and an inactive region encapsulating the active regions on the substrate;
- removing one or more portions of the inactive region between adjacent active regions to form a plurality of discrete emitter sections in the light emitting material;
- and
- removing one or more portions of the substrate to electrically and physically isolate each discrete emitter section from an adjacent discrete emitter section to prevent indium migration between adjacent discrete emitter sections.
