Purcell Effect in Epsilon-Near-Zero Microcavities.

ABSTRACT: Epsilon-near-zero (ENZ) photonics offers a compelling platform for integrated photonic systems, enabling a range of novel and extraordinary functionalities. However, the practical deployment of ENZ-based devices is constrained by high material losses and severe impedance mismatch, which are detrimental to applications requiring coherent light manipulation and efficient light-matter interaction. To address these challenges, we demonstrate that all-dielectric Bragg-reflection microcavities operated near their cutoff frequency, offer an ultralow-loss platform for enhancing light-matter interaction and exploring emission processes in the ENZ regime. While Bragg cavities are well-established, their potential as ENZ resonant microcavities remains largely unexplored. We investigate the Purcell ef
