Waveguide Coupling of an Integrated Nanowire Laser on Silicon with Enhanced End-Facet Reflectivity

We numerically explored the coupling characteristics and the critical interplay with the end-facet reflectivities of nanowire lasers coupled to proximal silicon-waveguides. A proper waveguide design enables high coupling efficiencies with enhanced end-facet reflectivities of
