Folded cavity surface-emitting laser

摘要

A surface-emitting laser is disclosed. The laser includes a first confinement cladding layer and a second confinement cladding layer. The laser also includes an active gain area between the first and second confinement cladding layers. The laser also includes a first reflector assembly and a second reflector assembly. The first reflector assembly is adjacent the first confinement cladding layer and includes a polyhedral prism waveguide having a non-reflecting surface facing the first confinement cladding layer. The first reflector assembly includes at least one totally-reflecting surface for transversely redirecting incident photonic emissions to a different longitudinal location of the polyhedral prism waveguide. The second reflector assembly is between the active gain area and the second reflector assembly.
