Abstract

Oxide-confinement has changed the design approach to realize low threshold, high efficiency vertical-cavity surface-emitting lasers (VCSELs). Numerous record results have resulted including ultralow threshold currents, high wall-plug efficiency (60 %), and high speed (20 GHz). However, the aperture approach so effectively demonstrated with selective oxidation extends beyond low threshold VCSELs and represents a new means of controlling optical modes in otherwise planar, Fabry-Perot microcavities
