The vertical-cavity surface-emitting laser (VCSEL / ˈvɪksəl /) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called in-plane lasers) which emit from surfaces formed by cleaving. A Vertical-Cavity Surface-Emitting Laser (VCSEL) is a type of semiconductor-based laser diode that emits light perpendicular from its top surface. Unlike traditional edge-emitting lasers, VCSELs emit the laser beam vertically, revolutionizing optical communication and optoelectronic technology. In. Vertical-cavity surface-emitting lasers (VCSELs) having a small aperture and operating in a single transverse mode (SM) are known to reach high relaxation oscillation frequencies of 30-90GHz and, thus, can offer intrinsic modulation bandwidth beyond 100GHz, once photon damping and electric. Vertical cavity surface-emitting lasers (VCSELs) are a monolithic kind of semiconductor lasers with beam emission perpendicular to the wafer surface. Despite their low manufacturing costs, diffraction-limited, narrow-band emission and excellent modulation capability, VCSELs were only used for optical data transmission. An ultraviolet light source with the small footprint and excellent optical characteristics of vertical-cavity surface-emitting lasers (VCSELs) may enable new applications in all these areas.
