The vertical-cavity surface-emitting laser, or VCSEL 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. High performance VCSEL array structures with square mesas are modeled by applying a steady-state 3-D heat dissipation model. As one can see, in. Conventional VCSEL arrays are mounted on a submount and use bond wires for electrical connections. Latest News from Vixar Inc.
