Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminish ....Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminishes performance. Here, we propose a new and unique nanostructure positioning technique incorporated directly into the growth process. It interfaces bottom-up technologies with device fabrication, facilitating incorporation of nanostructures in photonic devices, and may be transferrable to a variety of other systems.Read moreRead less
