Claim Text:
1. An apparatus, comprising: exactly one wide stripe semiconductor waveguide which is cleaved at a Talbot length thereof, the wide stripe semiconductor waveguide being defined by transverse index steps and having facets with mirror coatings and a predetermined laser diode structure; and a system for selectively pumping the wide stripe semiconductor waveguide to create and support an electric field distribution comprising a diffraction limited transverse Talbot mode, the system comprising a layer of silicon nitride (SiN) on a surface of the wide stripe semiconductor waveguide, the system further comprising patterning vias in the layer of SiN where current injection is desired, the layer of SiN and the surface of the wide stripe semiconductor waveguide covered with ohmic metal.
