Hanbury Brown - Twiss type correlations with surface plasmon light

TL;DR

This paper investigates intensity correlations of surface plasmon light, revealing non-classical photon statistics and a transition from antibunching to bunching, supported by experimental data and new theoretical analysis.

Contribution

It introduces a novel theoretical framework to analyze intensity correlations in surface plasmon light and experimentally demonstrates non-classical photon behavior.

Findings

Observation of non-classical photon statistics

Transition from antibunching to bunching in electron counts

Experimental validation of theoretical predictions

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 the transition from antibunching to bunching of the electron counts have been found experimentally and analysed on a new theoretical basis.
