Self-assembled quantum dot structures in a hexagonal nanowire for quantum photonics

Abstract

Two types of quantum nanostructures based on self-assembled GaAs quantumdots embedded into GaAs/AlGaAs hexagonal nanowire systems are reported, opening a new avenue to the fabrication of highly efficient single-photon sources, as well as the design of novel quantum optics experiments and robust quantum optoelectronic devices operating at higher temperature, which are required for practical quantum photonics applications.

Keywords: cavity; quantum dots; quantum photonics; self-assembled nanowires; single photon emitters.
