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…
Supertoroidal light pulses: Propagating electromagnetic skyrmions in free space
Yijie Shen, Yaonan Hou, Nikitas Papasimakis +1
Topological structures of electromagnetic fields could give access to nontrivial light-matter interactions and additional degrees of freedom for information and energy transfer. A…
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…
Observation of Toroidal Pulses of Light
A. Zdagkas, Y. Shen, C. McDonnell +5
The transverse electromagnetic waves are major information and energy carriers. In 1996, Hellwarth and Nouchi theoretically identified a radically different, non-transverse type of…
Spatio-temporal characterization of ultrashort vector pulses
Apostolos Zdagkas, Venkatram Nalla, Nikitas Papasimakis +1
Ultrafast vectorially polarized pulses have found many applications in information and energy transfer owing mainly to the presence of strong longitudinal components and their spac…
