Abstract

Semiconductor quantum dots embedded into nanophotonic resonators are one of the best performing sources for single and entangled photons. For certain protocols a defined charge in the quantum dot is required and to increase the device yield, charge control is a desired feature of the nanophotonic structure. In this paper, we present our latest efforts towards such a highly efficient, charge tunable device. Numerical simulations optimizing a bridged circular Bragg grating are discussed and photoluminescence measurements of a charge tunable quantum dot are shown.
