Optical levitation of microdroplet containing a single quantum dot

Preprint English OPEN
Minowa, Yosuke; Kawai, Ryoichi; Ashida, Masaaki;

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... View more
