Hanbury Brown–Twiss type correlations with surface plasmon light

Abstract

Intensity–intensity correlations are studied for light signals stemming from the spontaneous decay of surface plasmon oscillations, generated in the Kretschmann geometry. Non-classical photon statistics and the transition from antibunching to bunching of the electron counts have been found experimentally and analysed on a new theoretical basis.

Correlations in Intensity Fluctuations From a Quasi-Thermal Light Source: An Application of Hanbury Brown & Twiss

Christopher Watanabe

In this experiment, the observation by Hanbury Brown and Twiss that light intensity fluctuations from an extended broadband source are spatially correlated is demonstrated with a quasi-thermal light source. Laser light is used to illuminate a ground glass screen and generate a diffraction pattern, also known as a speckle pattern. The speckle pattern is recorded using an electronic camera and analyzed. Calculated auto-correlations of the intensity fluctuations agree with theoretical results originating from speckle analysis.

Hanbury-Brown and Twiss Interferometry with Interacting Photons

Yaron Bromberg, Yoav Lahini, Yaron R. Silberberg

We experimentally study the effect of interactions between photons on Hanbury- Brown and Twiss interefrometry. We measure intensity correlations of light propagating in a nonlinear medium, and discuss the effect of attractive and repulsive interactions.

Observation of Antinormally Ordered Hanbury Brown–Twiss Correlations

Koji Usami, Yoshihiro Nambu, Bao‐Sen Shi +2 more

We have measured antinormally ordered Hanbury Brown-Twiss correlations for coherent states of the electromagnetic field by using a stimulated parametric down-conversion process. Photons were detected by stimulated emission, rather than by absorption, so that the detection responded not only to actual photons but also to zero-point fluctuations via spontaneous emission. The observed correlations were distinct from normally ordered ones as they showed excess positive correlations, i.e., photon bunching effects, which arose from the thermal nature of zero-point fluctuations.

Light of Two Atoms in Free Space: Bunching or Antibunching?

Sebastian Wolf, Stefan Richter, Joachim von Zanthier +1 more

Photon statistics divides light sources into three different categories, characterized by bunched, antibunched, or uncorrelated photon arrival times. Single atoms, ions, molecules, or solid state emitters display antibunching of photons, while classical thermal sources exhibit photon bunching. Here we demonstrate a light source in free space, where the photon statistics depends on the direction of observation, undergoing a continuous crossover between photon bunching and antibunching. We employ two trapped ions, observe their fluorescence under continuous laser light excitation, and record spatially resolved the autocorrelation function g^{(2)}(τ) with a movable Hanbury Brown and Twiss detector. Varying the detector position we find a minimum value for antibunching, g^{(2)}(0)=0.60(5) and a maximum of g^{(2)}(0)=1.46(8) for bunching, demonstrating that this source radiates fundamentally different types of light alike. The observed variation of the autocorrelation function is understood in the Dicke model from which the observed maximum and minimum values can be modeled, taking independently measured experimental parameters into account.

Observation of interference pattern in the intensity correlation of a non-local object using a Hanbury Brown and Twiss-type experiment

Itamar Vidal, D. P. Caetano, E. J. S. Fonseca +1 more

We report on the experimental observation of interference pattern of a distributed double-slit, consisting of a single-slit and a wire spatially separated, illuminated by two beams from a pseudothermal light source, in Hanbury Brown and Twiss–like configuration. The interference pattern is obtained performing a classical correlation with the intensities of the light beams scattered by each part of the double-slit. A theoretical analysis confirms our experimental results, showing that classical correlations can also mimic non-local properties analogue to those using twin photons for quantum images.

Photon Statistic Measurements of Surface Plasmon Excitation

Dániel Oszetzky, Attila Nagy, Attila Kerekes +1 more

In this study we present the results of our measurements on photon statistic distributions of the light emitted by surface plasmon oscillations. Time interval statistics, photon-number distribution, auto-correlation and cross-correlation functions of the generated light were determined and compared to those of the exciting laser.
