All-optical sensing of a single-molecule electron spin
A. O. Sushkov, N. Chisholm, I. Lovchinsky +8
We demonstrate an all-optical method for magnetic sensing of individual molecules in ambient conditions at room temperature. Our approach is based on shallow nitrogen-vacancy (NV)…
Optical Lattices with Micromechanical Mirrors
K. Hammerer, K. Stannigel, C. Genes +5
We investigate a setup where a cloud of atoms is trapped in an optical lattice potential of a standing wave laser field which is created by retro-reflection on a micro-membrane. Th…
Fluctuating nanomechanical systems in a high finesse optical microcavity
I. Favero, S. Stapfner, D. Hunger +5
Confining a laser field between two high reflectivity mirrors of a high-finesse cavity can increase the probability of a given cavity photon to be scattered by an atom traversing t…
Micro-cavity length stabilization for fluorescence enhancement using schemes based on higher order spatial modes
A. Shehata Abdelatief, A. J. Renders, M. Alqedra +4
We report on experimental investigation of potential high-performance cavity length stabilization using odd-indexed higher-order spatial modes. Schemes based on higher-order modes…
Cryogenic platform for coupling color centers in diamond membranes to a fiberbased microcavity
M. Salz, Y. Herrmann, A. Nadarajah +6
We operate a fiberbased cavity with an inserted diamond membrane containing ensembles of silicon vacancy centers (SiV) at cryogenic temperatures K. The setup, sample f…
A stable fiber-based Fabry-Perot cavity
T. Steinmetz, A. Balocchi, Y. Colombe +4
We report the development of a fiber-based, tunable optical cavity with open access. The cavity is of the Fabry-Perot type and is formed with miniature spherical mirrors positioned…
Cavity-enhanced optical detection of carbon nanotube Brownian motion
S. Stapfner, L. Ost, D. Hunger +3
Optical cavities with small mode volume are well-suited to detect the vibration of sub-wavelength sized objects. Here we employ a fiber-based, high-finesse optical microcavity to d…
Resonant coupling of a Bose-Einstein condensate to a micromechanical oscillator
D. Hunger, S. Camerer, T. W. Haensch +4
We report experiments in which the vibrations of a micromechanical oscillator are coupled to the motion of Bose-condensed atoms in a trap. The interaction relies on surface forces…
