Introduction Vertical-Cavity Surface-Emitting Laser (VCSEL) is a type of semiconductor laser with output beam perpendicular from the top surface instead of from the cleaved edge of a wafer as a conventional edge-emitting laser (EEL).he quantum well (QW) in figure 1 acts as the gain medium inside of an ac-tive region with a thickness of a few wavelengths. This active region is in between of lower distributed Bragg reflectors (DBRs) and upper DBRs which are electrically con-ductive layer stacks performing as laser mirrors.
