Rabi oscillations of two-photon states in nonlinear optical resonators

TL;DR

This paper investigates Rabi-like oscillations in photon numbers and correlations caused by four-wave mixing in nonlinear resonators, revealing transient behaviors and anti-bunched photon states under different pumping schemes.

Contribution

It demonstrates the occurrence of Rabi oscillations and anti-bunching in photon states within nonlinear optical resonators, highlighting new dynamics in entangled photon generation.

Findings

Rabi-like oscillations observed in photon occupation and correlations

Transient oscillations occur under continuous pumping

Pulsed pumping produces strongly anti-bunched photon states

Abstract

We demonstrate that four-wave mixing processes in high-quality non-linear resonators can lead to Rabi-like oscillations in photon occupation numbers and second-order correlation functions, being a characteristic feature of the presence of entangled photon pairs in the optical signal. In the case of a system driven by a continuous coherent pump, the oscillations occur in the transient regime. We show that driving the system with pulsed coherent pumping would generate strongly anti-bunched photon states.
