Densely-Spaced Laser Diode Configurations

摘要

A densely-spaced single-emitter laser diode configuration is created, by using a laser bar (or similar array configuration) attached to a submount component of a size sufficient to adequately support the enter laser structure. The surface of the submount component upon which the laser structure is attached is metallized and used to form the individual electrical contacts to the laser diodes within the integrated laser structure. Once attached to each other, the laser structure is singulated by creating vertical separations between adjacent light emission areas. The submount metallization is similarly segmented, creating separate electrodes that are used to individually energize their associated laser diodes.

1. An optical system including densely-spaced light sources comprising
a plurality of separate single-emitter laser diodes; and a submount comprising a substrate of heatsinking material and a plurality of separate metallization regions disposed in a densely-spaced configuration along a top surface of the substrate, each separate single-emitter laser diode disposed over and contacted to a separate one of the plurality of separate metallization.
