Electrically switchable vacancy state revealed by in-operando positron experiments
Ric Fulop, Laurence Lyons, Robert Nick +6
Whether the flash state in electrically driven solids involves non-equilibrium defect production or is accounted for by Joule heating alone has been debated since 2010. Using posit…
Diamond Mirrors for High-Power Lasers
H. Atikian, N. Sinclair, P. Latawiec +12
High-power lasers have numerous scientific and industrial applications. Some key areas include laser cutting and welding in manufacturing, directed energy in fusion reactors or def…
Supercontinuum generation in angle-etched diamond waveguides
Amirhassan Shams-Ansari, Pawel Latawiec, Yoshitomo Okawachi +8
We experimentally demonstrate on-chip supercontinuum generation in the visible region in angle etched diamond waveguides. We measure an output spectrum spanning 670 nm to 920 nm in…
Quantum interference of electromechanically stabilized emitters in nanophotonic devices
Bartholomeus Machielse, Stefan Bogdanovic, Srujan Meesala +15
Photon-mediated coupling between distant matter qubits may enable secure communication over long distances, the implementation of distributed quantum computing schemes, and the exp…
Strain engineering of the silicon-vacancy center in diamond
Srujan Meesala, Young-Ik Sohn, Benjamin Pingault +16
We control the electronic structure of the silicon-vacancy (SiV) color-center in diamond by changing its static strain environment with a nano-electro-mechanical system. This allow…
Controlling the coherence of a diamond spin qubit through strain engineering
Young-Ik Sohn, Srujan Meesala, Benjamin Pingault +14
The uncontrolled interaction of a quantum system with its environment is detrimental for quantum coherence. In the context of solid-state qubits, techniques to mitigate the impact…

Cavity-optomechanical systems realized in single-crystal diamond are poised to benefit from its extraordinary material properties, including low mechanical dissipation and a wide o…
Nanofluidics of Single-crystal Diamond Nanomechanical Resonators
V. Kara, Y. -I. Sohn, H. Atikian +3
Single-crystal diamond nanomechanical resonators are being developed for countless applications. A number of these applications require that the resonator be operated in a fluid, i…
Enhanced strain coupling of nitrogen vacancy spins to nanoscale diamond cantilevers
Srujan Meesala, Young-Ik Sohn, Haig A. Atikian +4
Nitrogen vacancy (NV) centers can couple to confined phonons in diamond mechanical resonators via the effect of lattice strain on their energy levels. Access to the strong spin-pho…
