Enhancing the Radiative Rate in III-V Semiconductor Plasmonic Core-Shell Nanowire Resonators


We investigate the radiative properties of plasmonic core-shell nanowire resonators and, using boundary element method calculations, demonstrate enhanced radiative decay rate by up to 3500 times in nanoscale compound semi-conductor/metal cavities. Calculation of the local density of optical states enables identification of new types of modes in cavities with mode volumes on the order of 10^(-4)(λ/n)^3. These modes dramatically enhance the radiative decay rate and significantly modify the polarization of far-field emission.
