Normal mode splitting and purcell enhancement of local rayleigh scattering in a microsphere resonator

Abstract

Induced coupling between two counterpropagating modes in a microsphere resonator is studied under controllable conditions. A transition from weak to strong coupling is observed, similar to a coupled system composed of a single atom and a single cavity mode.

Observation of normal-mode splitting for an atom in an optical cavity

Robert J. Thompson, Gerhard Rempe, Harry J. Kimble

An investigation of the spectral response of a small collection of two-state atoms strongly coupled to the field of a high-finesse optical resonator is described for mean number N\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\le}10 atoms. For weak excitation, a coupling-induced normal-mode splitting is observed even for one intracavity atom, representing a direct spectroscopic measurement of the so-called vacuum Rabi splitting for the atom-cavity system.

Cavity-enhanced Rayleigh scattering

M. Motsch, Martin Zeppenfeld, Pepijn W. H. Pinkse +1 more

We demonstrate Purcell-like enhancement of Rayleigh scattering into a single optical mode of a Fabry–Perot resonator for several thermal atomic and molecular gases. The light is detuned by more than an octave, in this case by hundreds of nanometers, from any optical transition, making particle excitation and spontaneous emission negligible. The enhancement of light scattering into the resonator is explained quantitatively as an interference effect of light waves emitted by a classical driven dipole oscillator. Applications of our method include the sensitive, non-destructive in situ detection of ultracold molecules.

Coupling single atoms or molecules with a microsphere: a progress report

V. Lefèvre-Seguin

Silica microspheres have been demonstrated to provide a permanent resonator which combines small mode volumes with the highest observed quality factors (Q>2.10/sup 9/) corresponding to photon storage times of the order of one microsecond. These properties have allowed us to make a very low-threshold laser with Nd-doped silica microspheres (200 nW absorbed pump power, i.e. 10/sup 6/ excited ions/mode). These microlasers are now operated at 2 K to benefit from a smaller homogeneous linewidth. We then expect to reach the "thresholdless" regime with only a few excited ions. These experiments can also be considered as a first step toward Cavity QED experiments in the strong coupling regime with single atoms or molecules coupled to a whispering gallery mode.

Microcavities coupled to multilevel atoms

Sandra Isabelle Schmid, Jörg Evers

A three-level atom in the $\ensuremath{\Lambda}$ configuration coupled to a microcavity is studied. The two transitions of the atom are assumed to couple to different counterpropagating mode pairs in the cavity. We analyze the dynamics both in the strong-coupling and the bad-cavity limits. We find that, compared to a two-level setup, the third atomic state and the additional control field modes crucially modify the system dynamics and enable more advanced control schemes. All results are explained using appropriate dressed-state and eigenmode representations. As potential applications, we discuss optical switching and turnstile operations and detection of particles close to the resonator surface.
