ABSTRACT:
A semiconductor gain medium has an active gain region with a partially patterned radiation diverging region. The partially patterned radiation diverging region may be created with spatial resistive regions formed in a portion of the radiation diverging region having a narrower width than in other portions of the diverging region where the propagating radiation has a greater width. The gain region may be an amplifier or, in addition to the amplifier, may include a resonator cavity, or operate as an unstable resonator.
