Abstract
Various geometries are investigated numerically to extract the maximum number of photons to the airside from a single quantum dot embedded in a metal/dielectric cladded GaAs cylindrical structure. At the optimum cylindrical diameter, we predict that 80% of the photons can be extracted to the air side with a photon collection efficiency of 39% (68%) for a numerical aperture of 0.5 (0.8). These numbers are obtained as the influences of the internal modes and the multimode contributions are minimized at and around the target wavelength. Such geometry, by achieving good photon extraction and collection, will enhance nonclassical light generation at near infrared wavelengths.
