Trapping a single atom in the evanescent field of a WGM-resonator [PDF]
EPJ Web of Conferences, 2022 We demonstrate the trapping of single atoms in the evanescent field of a whispering-gallery-mode (WGM) resonator with a standing wave optical dipole trap. We present our progress towards an improved trap loading scheme.

Reconfigurable Liquid Whispering Gallery Mode Microlasers [PDF]
Scientific Reports, 2016 AbstractEngineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface ...
