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…
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…
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…
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…
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…
