Arrays Of Vertical Cavity Surface-Emitting Lasers Go Commercial

New vertical cavity surface-emitting lasers (VCSELs) solve many of the problems that plague edge-emitting lasers by making a simple, but revolutionary, "right turn" to allow light emission perpendicular to the semiconductor wafer surface. VCSELs are patterned using standard integrated circuit fabrication techniques and "vertically" emit round low-divergence light beams.
