Vertical-cavity surface-emitting laser: Characters, History, Applications & Regions

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 the individual chip out of a wafer. VCSELs are used in…
