ABSTRACT:
In making a laser diode by a method which includes epitaxially depositing a plurality of layers of a semiconductor material on a substrate, the final outermost layer deposited is of a material which has a band-gap lower than the preceding adjacent layer, which readily accepts a conductivity modifier, which can be selectively etched from the preceding adjacent layer and which preferably has a lattice parameter substantially equal to that of the preceding adjacent layer. A conductivity modifier is then diffused along a narrow stripe into and through the outermost layer, into the preceding adjacent layer. The outermost layer is then etched away to expose the surface of the preceding adjacent layer and a metal contact is applied to the exposed surface.
