What is VCSEL?

A VCSEL (Vertical-Cavity Surface-Emitting Laser) is a type of semiconductor laser diode that emits light perpendicular to the surface of the semiconductor chip, unlike traditional edge-emitting lasers which emit light from the edge. VCSELs are commonly used in optical communication, laser printers, optical mice, and facial recognition systems due to their low cost, ease of testing, and efficient coupling to optical fibers.
