Abstract

We study the probe spectrum of light generated by spontaneous emission into the mode of a cavity QED system. The probe spectrum has a maximum on-resonance when the number of inverted atoms for an input drive is maximal. For a larger number of atoms N, the maximum splits and develops into a doublet, but its frequencies are different from those of the so-called vacuum Rabi splitting.

We investigate theoretically and experimentally spontaneous emission into the mode of a cavity QED system in the frequency domain. We show that the fluorescence spectrum differs significantly from the vacuum Rabi splitting.

Spontaneous emission from a moving atom in a standing-wave cavity

Wensheng Ren, H. J. Carmichael

The spectrum of spontaneously emitted photons from an atom interacting with a single cavity mode depends on the relative sizes of the mode coupling constant and the cavity loss rate. If the coupling constant is not too large, perturbation theory can he used to show that the atomic linewidth is either increased (enhanced spontaneous emission) or decreased (inhibited spontaneous emission) by the presence of the cavity. When the coupling constant is so large that perturbation theory cannot be used, the spontaneous- emission spectrum forms a doublet, with peaks located at the normal-mode frequencies for the coupled-dipole and cavity-mode oscillators (the so-called "vacuum" Rabi splitting).

Transmission spectra of an atom cavity

TAN WEI-HAN, Renhong Liu

A composite atom-cavity system exhibits complex behavior with respect to spontaneous emission, resonance fluorescence, and transmission spectra.1–3 An early investigation1 showed that for an atom in an ideal cavity, the spontaneous-emission spectra show a doublet splitting in the case of very weak excitation. This splitting, which arises from vacuum-field Rabi oscillation, is regarded as an inherently quantum phenomenon.1,2 However, recent experiments and theoretical analyses have demonstrated that the multiatom vacuum Rabi splitting may be regarded as a feature of linear dispersion theory.3 This approach is dramatically different from the one employed in QED descriptions of the problem.

Spontaneous emission in a cavity

Anatolii N Oraevsky

A brief review is given of theoretical and experimental investigations of the spontaneous emission from an atom in a resonator cavity. A theory of spontaneous emission from a two-level atom in free space and in a cavity is presented in a methodical unified manner. In a single-mode resonator the structure of the spectrum of the emitted photons is a singlet or a doublet, depending on the ratio of the cavity damping to the constant of the interaction of an atom with a field. The emission spectrum of an atom in a cavity with two modes with similar frequencies may have a triplet structure.

Observation of the Vacuum Rabi Spectrum for One Trapped Atom

Andreea Boca, Ryan Miller, Kevin M. Birnbaum +3 more

The transmission spectrum for one atom strongly coupled to the field of a high finesse optical resonator is observed to exhibit a clearly resolved vacuum Rabi splitting characteristic of the normal modes in the eigenvalue spectrum of the atom-cavity system. A new Raman scheme for cooling atomic motion along the cavity axis enables a complete spectrum to be recorded for an individual atom trapped within the cavity mode, in contrast to all previous measurements in cavity QED that have required averaging over 10(3)-10(5) atoms.

Enhanced spontaneous emission into the mode of a cavity QED system

M. L. Terraciano, R. Olson Knell, D. L. Freimund +3 more

We study the light generated by spontaneous emission into a mode of a cavity QED system under weak excitation of the orthogonally polarized mode. Operating in the intermediate regime of cavity QED with comparable coherent and decoherent coupling constants, we find an enhancement of the emission into the undriven cavity mode by more than a factor of 18.5 over that expected by the solid angle subtended by the mode. A model that incorporates three atomic levels and two polarization modes quantitatively explains the observations.
