Enhanced Purcell factor for nanoantennas supporting interfering resonances
نویسندگان
چکیده
We study the effect of coupled resonances and quasibound states in continuum (quasi-BICs) on Purcell factor dielectric resonant nanoantennas. analyze numerically interfering a nanodisk with without substrate when modes are to an emitter localized inside nanodisk, we quantify modal contributions also reconstructing radiation patterns system. It is revealed that can be boosted substantially for strong coupling quasi-BIC regime.

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...
متن کاملMapping the plasmon resonances of metallic nanoantennas.
We study the light scattering and surface plasmon resonances of Au nanorods that are commonly used as optical nanoantennas in analogy to dipole radio antennas for chemical and biodetection field-enhanced spectroscopies and scanned-probe microscopies. With the use of the boundary element method, we calculate the nanorod near-field and far-field response to show how the nanorod shape and dimensio...
متن کاملCavity resonances of metal-dielectric-metal nanoantennas.
We propose a new design of optical nanoantennas and numerically study their optical properties. The nanoantennas are composed of two cylindrical metal nanorods stacked vertically with a circular dielectric disk spacer. Simulation results show that when the dielectric disk is less than 5nm in thickness, such nanoantennas exhibit two types of resonances: one corresponding to antenna resonance, th...
متن کاملOptical scattering resonances of single and coupled dimer plasmonic nanoantennas.
The optical resonances of individual plasmonic dimer antennas are investigated using confocal darkfield spectroscopy. Experiments on an array of antennas with varying arm lengths and interparticle gap sizes show large spectral shifts of the plasmon modes due to a combination of geometrical resonances and plasmon hybridization. The resonances of the coupled-dimer antennas are considerably broade...
متن کاملEnhancing resonances of optical nanoantennas by circular gratings.
Optical plasmonic antennas allow for localizing and enhancing light at the nanoscale. To enhance the application opportunities of optical antennas, their quality factor needs to be substantially improved. Here, we numerically and experimentally demonstrate that the resonance of a dipolar metallic disc antenna can be enhanced by a circular grating that obeys the Bragg condition. The supporting g...
