| 摘要 |
A device and a system to fabricate a device including a semiconductor mesa extending from a semiconductor base, the semiconductor mesa comprising an optically-active semiconductor area and a top surface, conductive material disposed on the top surface of the mesa, and substantially optically-transparent material disposed on the conductive material and on the top surface, wherein a surface of the substantially optically-transparent material above the conductive material and the top surface is substantially planar. In some aspects, the semiconductor mesa includes a side wall with one or more exposed p-n junctions, and material is disposed on the side wall to cover the one or more exposed p-n junctions.
