GRAZING INCIDENCE SLAB SEMICONDUCTOR LASER SYSTEM AND METHOD

摘要

A semiconductor laser system is disclosed for providing a laser output signal along a first output path (51) responsive to an excitation signal being applied to a planar semiconductor gain medium (46). The semiconductor gain medium (46) includes quantum wells within a cavity path, and the cavity path extends at least through the semiconductor gain medium (46), is reflected by an interface that provides substantially total internal reflection and that is substantially parallel to the gain medium (46), back through the semiconductor gain medium, enters the semiconductor substrate (45), and then exits the semiconductor substrate (45).
