Abstract
A superheterojunction (SHJ) laser constructed from periodic structural semiconductor materials. The SHJ laser has approximately a thousand junctions which are planar and layered to provide gain in the plane of the layers. In addition, the device allows beam narrowing and beam steering of its output signal due to the multiple number of output sources with the ability to control the output phase of the combined sources.
