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…
Continuous feedback on a quantum gas coupled to an optical cavity
Katrin Kroeger, Nishant Dogra, Rodrigo Rosa-Medina +4
We present an active feedback scheme acting continuously on the state of a quantum gas dispersively coupled to a high-finesse optical cavity. The quantum gas is subject to a transv…
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…
