    FIGURE 1. This schematic diagram shows the configuration of the coupled InP microring/nanowire laser system. Lasing photons from the micro-ring cavity are coupled into the nanowire at the ring center, which functions as a directional antenna. The light coupling strength and the beam shape can be controlled by tuning the coupling gap (dcoupling) and the nanowire width (wa).
