The fluorescence spectrum of an atom strongly coupled to a cavity driven by squeezed light
Craig M. Savage · Quantum Optics Journal of the European Optical Society Part B · 1990
Squeezing a light beam incident on a cavity which is strongly coupled to a single atom is shown to change the width of the fluorescent sidebands of the atom. The sidebands are either broader or narrower than in the absence of squeezing depending on whether the driving field has excess or reduced amplitude fluctuations. Unlike previously reported effects the entire electromagnetic vacuum seen by the atom does not have to be squeezed for optimum effect. A single squeezed mode driving the cavity is sufficient.
