Abstract:
A lateral injection VCSEL comprisingupper and lower multi-layered mirrors forming a cavity resonator having a resonator axis perpendicular to said layer, an active region disposed within said resonator, a current guide structure for directing current through an aperture to said active region to generate stimulated emission of radiation that propagates along said axis, a portion of said radiation forming an output signal which emerges from said resonator, said structure including high conductivity upper and lower contact layers located on opposite sides of said active region, upper and lower electrodes disposed on said upper and lower contact layers, respectively, and on laterally opposite sides of said upper mirror, characterized on that a lateral portion of said lower contact later that extends under said upper electrode has relatively high resistivity, the remaining lateral portion of said lower contact layer having said high conductivity.
