This research establishes a novel solid-state quantum optics platform by enabling visible-to-mid-infrared control of light-matter interactions within hyperbolic media, effectively bypassing traditional low-loss limitations in polaritonic crystals. By demonstrating that strictly non-radiating "dark" sources can become active emitters through population dynamics, the study opens new pathways for ultra-strong coupling applications without relying on dipole transitions.
Bright Emission from Dark Sources in Hyperbolic Media
arXiv:2606.16071v1 Announce Type: cross Abstract: Hyperbolic media enable ultra-strong light-matter interactions through their extreme field localization and small mode volumes, but low-loss realizations are fundamentally limited to the mid-infrared, owing to the long lifetimes of optical phonons in high-quality crystals. Here we show that bright emitters operating at visible or near-infrared frequencies can be used to generate radiation in this regime by inducing mid-infrared population dynamics, thereby creating a source in the hyperbolic frequency band without a corresponding dipole transition. We demonstrate that even a source with vanishing dipole and higher multipole moments - strictly non-radiating in any isotropic medium - becomes radiatively active in a hyperbolic environment. This enables visible and near-infrared control of light-matter interactions in polaritonic hyperbolic materials, establishing a new low-loss solid-state quantum optics platform.
