Engineering the Collapse of Lifetime Distribution of Nitrogen-Vacancy Centers in Nanodiamonds
Hao Li, Jun-Yu Ou, Behrad Gholipour +4
We demonstrate experimentally that the distribution of the decay rates of nitrogen-vacancy centers in diamond becomes narrower by over five times for nanodiamonds embedded in thin…

Decay rate enhancement of diamond NV-centers on diamond thin films
Hao Li, Jun-Yu Ou, Vassili A. Fedotov +1
We demonstrate experimentally two-fold enhancement of the decay rate of NV centers on diamond/Si substrate as opposed to a bare Si substrate. We link the decay enhancement to t…

Deeply Subwavelength Optical Imaging
Tanchao Pu, Jun-Yu Ou, Nikitas Papasimakis +1
We report the experimental demonstration of deeply subwavelength far-field optical imaging of unlabelled samples with resolution better than . We beat the ~/2 diffraction…
