Abstract
A surface emitting laser includes a conductive substrate, a metal bonding layer, a laser structure layer, an epitaxial semiconductor reflection layer, and an electrode layer. The laser structure layer has an epitaxial current-blocking layer having a current opening. Currents are transmitting through the current opening. The epitaxial current-blocking layer is grown by a semiconductor epitaxy process to confine the range of the currents to form electric fields.
