The frequency characteristics that determine the response rate of atomic narrow-band fluorescence filters are calculated. Atomic cesium and rubidium vapors are used as the working medium. The response rates of various filters are compared. The cesium filter at a wavelength of 456 nm turned out to be the best.

Frequency-filtered storage of parametric fluorescence with electromagnetically induced transparency

K. Akiba, K. Kashiwagi, T. Yonehara +1 more

The broadband parametric fluorescence pulse (probe light) with center frequency resonant on the $^{87}\mathrm{Rb}$ ${D}_{1}$ line was injected into a cold atomic ensemble with coherent light (control light). Due to the low gain in the parametric down conversion process, the probe light was in a highly bunched photon-pair state. By switching off the control light, the probe light within the electromagnetically induced transparency window was mapped on the atoms. When the control light was switched on, the probe light was retrieved and frequency-filtered storage was confirmed from the superbunching effect and an increase of the coherence time of the retrieved light.The broadband parametric fluorescence pulse (probe light) with center frequency resonant on the $^{87}\mathrm{Rb}$ ${D}_{1}$ line was injected into a cold atomic ensemble with coherent light (control light).

Multi-Mode Frequency Filtered Photon Correlations of a Driven Three-Level Ladder Atom

Jacob Ngaha, H. J. Carmichael

Resonance fluorescence and photon correlations are areas that have long been studied, and are integral to the field of quantum optics. Recently frequency filtered photon correlations and the method of frequency filtering have had a surge of interest [1]–[4]. In this work we develop a novel method of calculating frequency filtered photon correlations by coupling the atomic fluorescence - in this case, from a three-level ladder type atom [5], [6] - into an array of single-mode cavity filters. This coupling, modelled with an open cascaded systems approach [7], [8] is entirely unidirectional, allowing us to derive a closed set of coupled moment equations for the filter source operators. This provides an extremely efficient method for calculating frequency filtered second-order correlation functions.Resonance fluorescence and photon correlations are areas that have long been studied, and are integral to the field of quantum optics.
