摘要 |
A surface-emission laser diode of a vertical-cavity surface-emission laser structure includes a substrate and a mesa structure formed on the substrate, the mesa structure including therein a current confinement structure, wherein the current confinement structure includes a conductive current confinement region and an insulation region surrounding the conductive current confinement region, the insulation region being an oxide of a semiconductor material forming the conductive current confinement region, and wherein a center of the current confinement region is offset from a center of the mesa structure in a plane perpendicular to a laser oscillation direction.
