ABSTRACT:
The disclosure relates to integrated circuits of lasers, wherein the linear arrays are supplied in series, with a return of current through the substrate. When the substrate is semi-insulating, only the first epitaxially grown layer is conductive. To reduce its electrical resistance, a surface film of the substrate is made conductive by diffusion of a dopant. Application to power semiconductor lasers.
