a type of semiconductor LD with the laser beam emission perpendicular to the chip surface, in contrast to conventional edge-emitting semiconductor lasers where the laser light is emitted from the edge (usually formed by cleaving)
Vertical cavity surface emitting laser. A laser technology based on the methods of semiconductor manufacturing and packaging that enable high-volume manufacturing, lower-cost, and greater efficiencies.
vertical cavity surface emitting laser, a type of laser that emits light vertically out of the chip, not out the edge.
See vertical cavity surface-emitting laser. DC: Abbreviation for Volts, DC. Voltage using direct current. VDSL: Abbreviation for very high data rate digital subscriber line. A DSL operating at a data rate higher than that of HDSL. See also DSL.
The VCSEL (Vertical-Cavity Surface-Emitting Laser [v'ɪxl]) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.
