The quantum optical description of a Fabry-Perot interferometer and the prediction of an antibunching effect

TL;DR

This paper models a Fabry-Perot interferometer using quantum optics, predicting a non-classical antibunching effect with frequency-selected single photons, expanding understanding of quantum interference phenomena.

Contribution

It introduces a quantum optical model of the Fabry-Perot interferometer and predicts antibunching with non-identical frequency single photons.

Findings

Antibunching effect predicted for frequency-selected single photons

Model treats the interferometer as a frequency-dependent beam splitter

Antibunching observable without frequency-selective counters

Abstract

In this paper we describe a Fabry-Perot interferometer in the language of quantum optics. We go on to model the Fabry-Perot interferometer as a beam splitter having frequency dependent transmissivity and reflectivity coefficients. The antibunching, a totally non-classical effect, is to be expected if one excites this interferometer with carefully frequency-selected single photons arriving simultaneously from opposite directions. Contrary to a normal beam splitter, even slightly different frequency single photons should be able to show this effect, as long as the photon counters are not frequency selective.
