Broadband Purcell enhancement in plasmonic ring cavities

We present a theoretical study of a surface plasmon ring resonator geometry that shows strong spontaneous emission control due to an extremely small optical cavity mode volume. V grooves made in the surface of a metal confine whispering gallery surface plasmon polariton modes at the bottom of the groove, with the confinement determined by groove depth and width. Resonances in ringlike cavities ...

Probing the mechanisms of large Purcell enhancement in plasmonic nanoantennas

To move nanophotonic devices such as lasers and single-photon sources into the practical realm, a challenging list of requirements must be met, including directional emission1–5, room-temperature and broadband operation6–9, high radiative quantum efficiency1,4 and a large spontaneous emission rate7. To achieve these features simultaneously, a platform is needed for which the various decay chann...
