ABSTRACT:
The specification describes an improved form of heterostructure laser, termed a "Rib-Loc" laser. It is an easily fabricated device with desirable electrical and optical properties. The Rib-Loc is simple to fabricate because a single, self-aligned rib provides ohmic contact, current confinement and lateral waveguiding. A deeply etched P-cladding layer outside the rib provides the positive index change needed for an index-guided laser. The large optical cavity increases the maximum power output and reduces the aspect ratio of the beam.
