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…
Infrared laser magnetometry with a NV doped diamond intracavity etalon
Yannick Dumeige, Jean-François Roch, Fabien Bretenaker +8
We propose an hybrid laser system consisting of a semiconductor external cavity laser associated to an intra-cavity diamond etalon doped with nitrogen-vacancy color centers. We con…
Multiphoton-Excited Fluorescence of Silicon-Vacancy Color Centers in Diamond
James M. Higbie, John D. Perreault, Victor M. Acosta +7
Silicon-vacancy color centers in nanodiamonds are promising as fluorescent labels for biological applications, with a narrow, non-bleaching emission line at 738\,nm. Two-photon exc…
Microwave saturation spectroscopy of nitrogen-vacancy ensembles in diamond
P. Kehayias, M. Mrózek, V. M. Acosta +5
Negatively-charged nitrogen-vacancy (NV) centers in diamond have generated much recent interest for their use in sensing. The sensitivity improves when the NV ground-state micr…
Magnetometry with nitrogen-vacancy ensembles in diamond based on infrared absorption in a doubly resonant optical cavity
Yannick Dumeige, Mayeul Chipaux, Vincent Jacques +8
We propose to use an optical cavity to enhance the sensitivity of magnetometers relying on the detection of the spin state of high-density nitrogen-vacancy ensembles in diamond usi…
Coupling of Nitrogen-Vacancy Centers to Photonic Crystal Cavities in Monocrystalline Diamond
Andrei Faraon, Charles Santori, Zhihong Huang +2
The zero-phonon transition rate of a nitrogen-vacancy center is enhanced by a factor of ~70 by coupling to a photonic crystal resonator fabricated in monocrystalline diamond using…
