Large spontaneous emission enhancement in plasmonic nanocavities
Cavity–emitter coupling can enable a host of potential applications in quantum optics, from low-threshold lasers to brighter single-photon sources for quantum cryptography1. Although some of the first demonstrations of spontaneous emission modification occurred in metallic structures2,3, it was only after the recent demonstration of cavity quantum electrodynamics effects in dielectric optical c...
متن کاملBroadband enhancement of spontaneous emission in a photonic-plasmonic structure.
We demonstrate that a broadband enhancement of spontaneous emission can be achieved within a photonic-plasmonic structure. The structure can strongly modify the spontaneous emission by exciting plasmonic modes. Because of the excited plasmonic modes, an enhancement up to 30 times is observed, leading to a 4 times broader emission spectrum. The reflectance measurement and the finite-difference t...
متن کاملBroadband 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 ...
متن کاملProbing 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...
متن کاملSpontaneous Emission Extraction and Purcell Enhancement from Thin-Film 2-D Photonic Crystals
Electromagnetic band structure can produce either an enhancement or a suppression of spontaneous emission from two-dimensional (2-D) photonic crystal thin films. We believe that such effects might be important for light emitting diodes. Our experiments were based on thin-film InGaAs/InP 2-D photonic crystals at ambient temperature, but the concepts would apply equally to InGaN thin films, for e...
