Abstract

Controlled manipulation of quantum dots with nanometer precision is an essential capability for basic science as well as for scalable engineering of nanophotonic and quantum optical devices. The most common methods for manipulation of particles use optical or dielectric trapping forces which scale poorly with particle size, making it difficult to manipulate single quantum dots. Here we demonstrate a particle manipulation technique that achieves nanometer positioning by controlling the flow of the surrounding liquid. This approach scales much more favorable with particle size, enabling the position of colloidal quantum dots with better precision. Using this approach we demonstrate the capture, quantum optical characterization, and manipulation of individually selected single quantum dots with up to 45.5 nm precision for times exceeding one hour. This technique can be used to place pre-selected single photon sources in nanophotonic structures such as cavities and waveguides for engineering of integrated quantum optical devices.
