Extended Single-Atom Tweezer Arrays in High-Cooperativity Cavity-QED
Thomas Picot, Clément Raphin, Marcel Kern +4
A central challenge for cavity-QED-based quantum technologies is to make high-cooperativity optical interfaces compatible with site-resolved arrays of single atoms. Here, we demons…
Spectral Engineering of Cavity-Protected Polaritons in an Atomic Ensemble with Controlled Disorder
Mohamed Baghdad, Pierre-Antoine Bourdel, Sylvain Schwartz +3
The paradigm of quantum emitters coupled to a single cavity mode appears in many situations ranging from quantum technologies to polaritonic chemistry. The ideal case of identi…
An optical elevator for precise delivery of cold atoms using an acousto-optical deflector
Francesco Ferri, Arthur La Rooij, Claire Lebouteiller +6
We implement a simple method for fast and precise delivery of ultracold atoms to a microscopic device, i.e. a Fabry-Perot microcavity. By moving a single beam optical dipole trap i…
Overlapping two standing-waves in a microcavity for a multi-atom photon interface
Sébastien Garcia, Francesco Ferri, Jakob Reichel +1
We develop a light-matter interface enabling strong and uniform coupling between a chain of cold atoms and photons of an optical cavity. This interface is a fiber Fabry-Perot cavit…
Mapping standing-wave cavity modes with a commercial scanning near-field microscope tip
Francesco Ferri, Sébastien Garcia, Mohamed Baghdad +2
We describe a method to map the standing-wave pattern inside a Fabry-Perot optical cavity with sub-wavelength resolution by perturbing it with a commercially available scanning nea…
Dual-wavelength fiber Fabry-Perot cavities with engineered birefringence
Sébastien Garcia, Francesco Ferri, Konstantin Ott +2
We present a method to engineer the frequency splitting of polarization eigenmodes in fiber Fabry-Perot (FFP) cavities. Using specific pattern of multiple CO laser pulses, we m…
Compensating fictitious magnetic field gradients in optical microtraps by using elliptically polarized dipole light
Sébastien Garcia, Jakob Reichel, Romain Long
Tightly focused optical dipole traps induce vector light shifts ("fictitious magnetic fields") which complicate their use for single-atom trapping and manipulation. The problem can…
Millimeter-long Fiber Fabry-Perot cavities
Konstantin Ott, Sebastien Garcia, Ralf Kohlhaas +4
We demonstrate fiber Fabry-Perot (FFP) cavities with concave mirrors that can be operated at cavity lengths as large as 1.5mm without significant deterioration of the finesse. This…
Fiber-pigtailed optical tweezer for single-atom trapping and single-photon generation
Sébastien Garcia, Dominik Maxein, Leander Hohmann +2
We demonstrate a miniature, fiber-coupled optical tweezer to trap a single atom. The same fiber is used to trap a single atom and to read out its fluorescence. To obtain a low back…
Enhanced and reduced atom number fluctuations in a BEC splitter
Kenneth Maussang, G. Edward Marti, Tobias Schneider +6
We measure atom number statistics after splitting a gas of ultracold 87Rb atoms in a purely magnetic double-well potential created on an atom chip. Well below the critical temperat…
Cavity-based single atom preparation and high-fidelity hyperfine state readout
Roger Gehr, Jürgen Volz, Guilhem Dubois +6
We prepare and detect the hyperfine state of a single 87Rb atom coupled to a fiber-based high finesse cavity on an atom chip. The atom is extracted from a Bose-Einstein condensate…
Tunable whispering gallery modes for spectroscopy and CQED experiments
Wolf von Klitzing, Romain Long, Vladimir S. Ilchenko +2
We have tuned the whispering gallery modes of a fused silica micro- resonator over nearly 1 nm at 800 nm, i.e.over half of a free spectral range or the equivalent of 10^6 linewidth…
Frequency tuning of the whispering gallery modes of silica microspheres for CQED and spectroscopy
Wolf von Klitzing, Romain Long, Vladimir S. Ilchenko +2
We have tuned the whispering gallery modes of a fused silica microresonator over nearly 1 nm at 800 nm, i.e. over 0.5 FSR or 10^6 linewidths of the resonator. This has been achieve…
