Generation of N00N-like interferences with two thermal light sources
Daniel Bhatti, Anton Classen, Raimund Schneider +2
Measuring the th-order intensity correlation function of light emitted by two statistically independent thermal light sources may display N00N-like interferences of arbitrary or…
Directional Dicke Subradiance with Nonclassical and Classical Light Sources
Daniel Bhatti, Raimund Schneider, Steffen Oppel +1
We investigate Dicke subradiance of distant quantum sources in free space, i.e., the spatial emission pattern of spontaneously radiating non-interacting multi-level atoms or multi-…
An optical multimode fiber as pseudothermal light source
Thomas Mehringer, Steffen Oppel, Joachim von Zanthier
We report on a novel pseudothermal light source based on laser light coupled into an optical multimode fiber. The setup is simple, of low cost, exhibits inherently high directional…
Simulating Dicke like superradiance with classical light sources
D. Bhatti, S. Oppel, R. Wiegner +2
In this paper we investigate the close relationship between Dicke superradiance, originally predicted for an ensemble of two-level atoms in entangled states, and the Hanbury Brown…
Simulating superradiance from higher-order-intensity-correlation measurements: Single atoms
R. Wiegner, S. Oppel, D. Bhatti +2
Superradiance typically requires preparation of atoms in highly entangled multi-particle states, the so-called Dicke states. In this paper we discuss an alternative route where we…
Hong-Ou-Mandel interference without beam splitters
S. Mährlein, S. Oppel, R. Wiegner +1
We propose a new interferometric setup which displays a completely destructive generalized N-photon Hong-Ou-Mandel interference. The key property of this scheme is that is does not…
Nonlocal photon correlations and violation of Bell inequalities for spatially separated classical light fields
Daniel Bhatti, Raimund Schneider, Thomas Mehringer +2
It is theoretically and experimentally shown that photons emitted by statistically independent incoherent classical light sources and measured in the far field in spatially separat…
Directional superradiant emission from statistically independent incoherent non-classical and classical sources
S. Oppel, R. Wiegner, G. S. Agarwal +1
Superradiance is one of the outstanding problems in quantum optics since Dicke introduced the concept of enhanced directional spontaneous emission by an ensemble of identical two-l…
Isotope shifts and hyperfine structure of the Fe I 373.7 nm resonance line
S. Krins, N. Huet, T. Bastin
We report measurements of the isotope shifts of the 3d6 4s2 a 5D3 - 3d6 4s4p z 5F4o FeI resonance line at 373.7 nm between all four stable isotopes 54Fe, 56Fe, 57Fe and 58Fe, as we…
Measurement induced focussing of radiation from independent single photon sources
R. Wiegner, S. Oppel, J. von Zanthier +1
We present a technique based on multi-photon detection which leads to a strong focussing of photons scattered by independent single photon emitters. For N single photon sources it…
Active laser frequency stabilization using neutral praseodymium (Pr)
S. Oppel, G. H. Guthoehrlein, W. Kaenders +1
We present a new possibility for the active frequency stabilization of a laser using transitions in neutral praseodymium. Because of its five outer electrons, this element shows a…
Isotope shifts and hyperfine structure of the Fe I 372 nm resonance line
S. Krins, S. Oppel, N. Huet +2
We report measurements of the isotope shifts of the Fe I resonance line at 372 nm between all four stable isotopes Fe, Fe, $^{…
