Hybrid microcavity for superminiature single quantum dot based emitters

Abstract

This paper describes the development and implementation of a microcavity based on a semiconductor Bragg reflector and a microlens selectively positioned over a single (111) InGaAs quantum dot. The structure of the microcavity ensures effective pumping of quantum dots and high external quantum emission output efficiency. This microcavity can be used to create single photon emitters and emitters of entangled photon pairs based on single semiconductor quantum dots.
