Fluorescence from a single atom interacting with antibunched light

Abstract

Statistical properties of fluorescent light from a single two-level atom driven by a beam of antibunched light are discussed in the weak field limit. Fields generated by realistic open systems with pumping and dissipation are chosen to be the models for antibunched light. As examples, we consider fields produced in intracavity second harmonic generation and in the homodyned degenerate parametric oscillator. These fields can be described in terms of real Gaussian random processes with coherent components. Analytical expressions for fluorescent light intensity and second order intensity correlation function in the steady state are derived. Effects of driving field correlations, detuning, and parameters characterizing the driving field on the statistics of scattered light are investigated. It is found that over a certain range of parameters characterizing the driving field the second order intensity correlation function may vanish at non-zero time. These and other interesting features will be discussed.

Single-atom fluorescence with nonclassical light

Irina E. Lyublinskaya, Reeta Vyas

The statistical properties of fluorescent light from a single two-level atom driven by nonclassical light beams that exhibit antibunching and squeezing are discussed in the weak-field limit. The fields produced in intracavity second-harmonic generation and those produced by superposing the light from a degenerate parametric oscillator with a coherent field are considered to be the models of nonclassical light beams. These fields can be described in terms of real Gaussian random processes with nonzero mean coherent components. Analytical expressions for the fluorescent light intensity, the second-order intensity correlation function, and the variance of the photon number in the steady state are obtained. The effects of driving-field correlations, detuning, and other parameters characterizing the atom-field interaction on the statistics of scattered light are investigated. It is found that for a certain range of parameters the second-order intensity correlation function may vanish at nonzero times. Under certain other circumstances the antibunching of the fluorescent photons is enhanced. These and other interesting features that appear in the scattered light are discussed.

Resonance fluorescence with squeezed light excitation

Reeta Vyas, Surendra Singh

Resonance fluorescence from a single two-level atom driven by a beam of squeezed light is studied in the weak field limit. We consider the situation where the atom is coupled to the ordinary vacuum and only a few field modes corresponding to the driving field are squeezed. The field produced by the degenerate optical parametric oscillator is used as the driving field. This driving field can be described in terms of two real independent Gaussian processes. Heisenberg equations of motion are solved in the steady-state, and analytic expressions for the fluorescent light intensity and the spectrum of fluorescent light are derived. We also consider photon statistics of fluorescent light. In particular, squeezing, antibunching, and sub-Poissonian statistics of fluorescent photons are discussed and analytic expressions for the quadrature variance and the two-time intensity correlation function are presented. Contrary to the case of coherent excitation the second-order intensity correlation function does not factorize.

Statistical properties of the light scattered by a two-level atom driven by a resonant multimode laser beam

Martine Le Berre, Elisabeth Ressayre, Andree A. Tallet

A theory is presented of the near-resonant interaction of two-level atom with strong Gaussian fields. Analytical expressions are given for the fluorescence intensity and for the two-time first- and second-order correlation functions of the intensity in both cases of a chaotic field and a real Gaussian field. The usual three-peak structure in the fluorescence spectrum is found to disappear because the amplitude fluctuations of the driving light prevent the nutation process. The scattered intensity is shown no longer to present a Markovian character when the atom is driven by a Gaussian field. The atom gains a sort of memory because of the intensity fluctuations in the driving field.

Nonclassical intensity correlations in cavity QED

Joe Leach, Perry R. Rice

We consider two systems in the weak driving field limit. The first is an optical parametric oscillator, the transmitted field of which is highly bunched. We discuss a conditioned measurement of the second order intensity correlation function that yields antibunching. The second system we consider is a single two level atom inside a weakly driven cavity. Here we consider cross correlations between the transmitted and fluorescent fields. A strong asymmetry in delay time has been noted by Denisov et. al., here we find strong violations of a classical inequality for the cross correlation.

Antibunching phenomena on single-scatterer fluorescence in the weak-field limit

A. A. Villaeys

Antibunching phenomena have been extensively discussed previously (1979) in the case of an intense driving field. Previously the intensity correlation function has been obtained in the so-called weak-field case by a limiting procedure. The author gives a description of weak light beams from a general light scattering point of view which has not been given previously. He shows that some specific phenomena like the indistinguishability of the photons or the wavepacket structure of the weak light beam have been neglected in earlier works by the use of their limiting procedure. He describes the scatterer rigorously, so the dynamical evolution is not restricted to the particular case of two-level atoms as in all previous work. Even with weak fields and a two-level system his result exhibits a supplementary contribution associated with the boson character of the photon. In addition the theory is extended to cover near-resonant phenomena.
