Modification and control of the spontaneous emission from an M-type atom embedded in an anisotropic photonic crystal

Chunling Ding, Jiahua Li, Xiaoxue Yang +1 more

We describe the spontaneous emission properties of an M-type five-level atom embedded in a photonic crystal (PC), which is coherently driven by two external laser fields. It leads to two types of quantum interference: reservoir-induced interference and laser-induced interference. Considering different detunings of atomic transition frequencies from band edges, we reveal some interesting phenomena such as spectral-line enhancement, spectral-line suppression, spectral-line narrowing, reservoir-induced cancellation of spontaneous emission and the appearance of dark lines, which originate from the quantum interference effects and the control of external laser fields. These investigations suggest possible applications in quantum optics, optical communications and in the fabrication of novel optoelectronic devices.

Effects of spontaneously generated coherence on the resonance fluorescence spectrum of a laser-driven four-level diamond-shape atomic system

Bao-Quan Ou, Lin-Mei Liang, Cheng-Zu Li

The resonance fluorescence spectra of a laser-driven four-level closed-loop diamond-shape atomic system are investigated in this paper. The four decay channels in the system interfere with each other in different ways according to several distinct arrangements of the two intermediate atomic levels, and hence produce the spontaneously generated coherence (SGC) effects. The numerical calculation shows that the amplitude, the linewidth and the number of sidebands of the resonance fluorescence spectrum are deeply modified by the SGC effects; accordingly, interesting effects such as the spectral-line narrowing, spectral-line suppression, spectral-line enhancement and even the complete quenching of fluorescence are generated under certain conditions. Moreover, we propose a new kind of level structure, the seesaw structure, in which the SGC effect can also be attained without the rigorous conditions of degenerate levels. In the end, we discuss the possibility of demonstrating our scheme in real atomic systems and summarize our results.

Suppression of fluorescence in a squeezed vacuum

Gordon Yeoman

A scheme which results in the simultaneous narrowing of all three spectral peaks of the Mollow triplet is proposed. In particular, we investigate the effect on resonance fluorescence of processing the squeezed output of an optical parametric oscillator by propagation through a linear dielectric. The frequency-dependent squeezing phase induced by this process is found to result in subnatural spectral widths for appropriate parameter choices. The line-narrowing mechanisms at the Rabi sidebands manifest themselves in the second-order correlation function of the fluorescent field which is found to decay at a subnatural rate. The potential for experimental realization of these phenomena is discussed.
