Abstract
The vertical-cavity surface-emitting laser (VCSEL) is a promising source for optical interconnection and communication networks, but is limited by the low efficiency and high series resistance that are caused in part by the potential barriers at the AlxGa1-xAs/AlAs heterojunction interfaces of its DBR mirrors. Various schemes have been used to grade these interfaces to reduce the energy barriers, with step-grading as the most common.
