Abstract We propose a hybrid microcavity design of a 1.3 μm range electrically driven single-photon source (SPS) consisting of two high-contrast dielectric distributed Bragg reflectors which surround a 3λ-thick semiconductor cavity with two intra-cavity contact layers and four 40-nm-thick oxide-confined apertures. According to 3D finite-difference time-domain modelling, the overall photon-extraction efficiency of ~74% and the Purcell factor of ~13 can be obtained by properly adjusting the position of oxide-confined apertures relative to the electric field of the fundamental optical mode. The studied SPS design also demonstrates a coupling efficiency of up to 13% within numerical aperture 0.12 in contrast to ~5% reached for a conventional semiconductor micropillar.

Abstract In this work, the finite difference time domain (FDTD) method has been utilized to simulate the propagation emission from PbS quantum dots in a hexagonal InP nanowire as a single photon source. The effect of height and radius of the nanowire as well as the location and orientation of the dipole source in the Purcell factor and Quality factor of the nanowire have been investigated. A broadband electric dipole source has been used to model the quantum dot and the effect of shape and radius of PbS quantum dot have been investigated in the final results. The conclusive structure has been optimized to a nanowire with hexagonal cross section with radius of 220nm and height of 10um. The emission peak obtained above 1um with Purcell factor of 4.72 which is in good agreement with cases have been used as single photon source in quantum communication.

In this paper, the characteristic and Purcell factor of a metal fan-rod antenna are analyzed theoretically. The antenna consists of a pair of fan-rod structures. The characteristic is obtained by the simulation method. The results show that the coupling areas and the geometries of the fan-rod antenna have great influence on the resonance wavelength. The Purcell factor is also analyzed with the change of optical wavelength which can enhance the collection efficiency of single photon source. The theories, simulations and calculations in this paper are important for the experimental operation of single photon source with nanoantenna.

Electrically-pumped optical microcavity single photon sources based on single quantum dots are investigated by numerical modelling techniques. Design of electrically driven 1.3 μm-range single photon source with intra-cavity contacts and multiply oxide aperture layers is proposed. About two times improvement in photon coupling efficiency into the single-mode fiber is demonstrated as compared with single photon source based on cylindrical micropillar.
