Enhancing the efficiency of quantum-dot-based single-photon source designs by suppressing background emission using concentric rings
Martin Arentoft Jacobsen, Luca Vannucci, Julien Claudon +2
In this paper, we theoretically demonstrate that a few-period circular Bragg reflector consisting of concentric rings placed around an infinite nanowire with an embedded quantum do…
