A VCSEL (vertical cavity surface-emitting laser) is a surface-emitting semiconductor light source that emits laser beams in a direction perpendicular to its top surface. In simple words, compared to conventional edge-emitting light diodes, VCSEL emits light or vertical beam from its top surface. Compared to conventional edge-emitting light diodes, VCSEL emits light or vertical beams from its top surface. VCSEL is one such laser that is largely used in various industrial and military applications. Individual VCSEL emitters are very small, typically around 10 microns in diameter, but collectively generate a much higher output power level. It is one such laser that is largely used in various industrial and military applications. This article discusses the basics of VCSEL, including definition, working and characteristics.
