Optical levitation of microdroplet containing a single quantum dot
arXiv:1409.0092 · doi:10.1364/OL.40.000906
Abstract
We demonstrate the optical levitation or trapping in helium gas of a single quantum dot (QD) within a liquid droplet. Bright single photon emission from the levitated QD in the droplet was observed for more than 200 s. The observed photon count rates are consistent with the value theoretically estimated from the two-photon-action cross section. This paper presents the realization of an optically levitated solid-state quantum emitter.
