Abstract
Highly compact vertical cavity surface emitting laser structures formed by a lateral oxidation process are provided. Specifically, well-controlled oxidized regions bound and define the aperture of a laser structure in a current controlling oxidation layer, wherein the aperture comprises a conductive region in the oxidation layer. These oxidized regions are formed by the use of a pre-defined bounding pattern of cavities etched in the laser structure, which allow the embedded oxidation layer to be oxidized, and which results in a highly reproducible and manufacturable process.
