Channel Plasmon Nanowire Lasers with V-Groove Cavities

A hybrid channel plasmon nanowire laser based on GaAs/AlGaAs core-shell semiconductor nanowire and silver V-groove is proposed. The laser structure has potential capability of integrating with plasmonic waveguides, using channel plasmon-polariton modes in V-groove plasmonic waveguides. Guiding and l...

description A hybrid channel plasmon nanowire laser based on GaAs/AlGaAs core-shell semiconductor nanowire and silver V-groove is proposed. The laser structure has potential capability of integrating with plasmonic waveguides, using channel plasmon-polariton modes in V-groove plasmonic waveguides. Guiding and lasing properties are numerically calculated using finite elements method. From the theoretical results, the laser could support guiding mode with a smallest diameter of 40 nm. Lasing emission could happen at a relatively low threshold around 2000 cm(− 1) when the diameter is larger than 140 nm. A quite large Purcell factor of 180 could be achieved to enhance the spontaneous emission rate.
