This paper presents a novel fabrication scheme for mesa-isolated monolithic vertical-cavity surface-emitting lasers (VCSELs) based on fully self-aligning processes. In the new design, heat extraction from the devices' active regions is strongly enhanced, resulting in record-low thermal resistances. The improved heat sinking does not introduce parasitics that would interfere with the dynamic properties...
We demonstrate novel pixel architectures in 2-D vertical-cavity surface-emitting laser (VCSEL) arrays offering additional functionality without sacrificing efficient fabrication, compactness, and low module cost. Very high flip chip VCSEL packing densities enable both a built-in 3-per-channel VCSEL redundancy as well as simple intracell VCSEL monitoring. Each pixel has three individually addressable...
