Robust optical readout and characterization of nuclear spin transitions in nitrogen-vacancy ensembles in diamond
A. Jarmola, I. Fescenko, V. M. Acosta +5
Nuclear spin ensembles in diamond are promising candidates for quantum sensing applications, including rotation sensing. Here we perform a characterization of the optically detecte…
Diamond magnetometer enhanced by ferrite flux concentrators
Ilja Fescenko, Andrey Jarmola, Igor Savukov +6
Magnetometers based on nitrogen-vacancy (NV) centers in diamond are promising room-temperature, solid-state sensors. However, their reported sensitivity to magnetic fields at low f…
Influence of nanostructuring on silicon vacancy center spins in diamond pillars
Thomas Lutz, Tamiko Masuda, John P. Hadden +4
Color centers in diamond micro and nano structures are under investigation for a plethora of applications. However, obtaining high quality color centers in small structures is chal…
Stimulated emission depletion microscopy with diamond silicon-vacancy centers
Yaser Silani, Forrest Hubert, Victor M. Acosta
The spatial resolution and fluorescence signal amplitude in stimulated emission depletion (STED) microscopy is limited by the photostability of available fluorophores. Here, we sho…
Achromatic varifocal metalens for the visible spectrum
Maxwell D. Aiello, Adam S. Backer, Aryeh J. Sapon +4
Metasurface optics provide an ultra-thin alternative to conventional refractive lenses. A present challenge is in realizing metasurfaces that exhibit tunable optical properties and…
Two-dimensional nuclear magnetic resonance spectroscopy with a microfluidic diamond quantum sensor
Janis Smits, Joshua Damron, Pauli Kehayias +7
Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear magnetic resonance (NMR) spectroscopy owing to their micron-…
