Monolithically integrated optically-pumped edge-emitting semiconductor laser

摘要

The invention features an edge-emitting semiconductor signal laser having an active region to produce laser light. There is provided a semiconductor pump laser monolithically integrated with the edge-emitting signal laser. The pump laser includes a photon emissive active region to provide photopumping of the active region of the edge-emitting signal laser, thereby providing optical excitation of the active region of the signal laser.
