ABSTRACT
Multibeam emission and spatial wavelength demultiplexing in semiconductor lasers by patterning their facets with plasmonic structures is reported. Specifically, a single-wavelength laser was made to emit beams in two directions by defining on its facet two metallic gratings with different periods. The output of a dual-color laser was spatially separated according to wavelength by using a single metallic grating. The designs can be integrated with a broad range of active or passive optical components for applications such as interferometry and demultiplexing.

    A detailed study of the effect of p-doping of the active region on characteristics of long-wavelength InAs/GaAs QD lasers is performed. As the doping level increases, the characteristic temperature rises and the range of temperature stability for the threshold current density is broadened. In a...
