ABSTRACT:
A laser diode array in which a conductive layer is provided over a nonconductive or insulating layer, grooves being formed in the conductive layer, and laser diodes being disposed in the grooves. In one embodiment, the layers are separate; in another embodiment, the conductive and nonconductive layers are provided in the same monolithic substrate, which may be undoped semiconductor material such as silicon, with a highly doped upper portion in which the grooves are formed. In another embodiment of the array, the diodes are mounted in the grooves such that at least a portion of their light is emitted towards a bottom of the array.
