Signature of strong atom-cavity interaction on critical coupling

TL;DR

This paper investigates how resonant atom-cavity interactions influence critical coupling in a cavity with metamaterial mirrors, revealing a splitting of the critical coupling dip due to strong coupling effects.

Contribution

It demonstrates the impact of strong atom-cavity coupling on critical coupling phenomena, introducing a novel explanation based on frequency and lifetime splitting.

Findings

Resonant atom-cavity interaction causes splitting of the critical coupling dip.

The splitting is explained through frequency and lifetime analysis.

Strong coupling modifies the critical coupling behavior.

Abstract

We study a critically coupled cavity doped with resonant atoms with metamaterial slabs as mirrors. We show how resonant atom-cavity interaction can lead to a splitting of the critical coupling dip. The results are explained in terms of the frequency and lifetime splitting of the coupled system.
