Controlling Radiative Properties of Circular Atomic Arrays through Nanofiber Guided Modes

Year: 2026

Type: conference-paper

Abstract: We theoretically investigate the collective emission of one and two circular arrays of two-level atoms surrounding an optical nanofiber (ONF). Our study reveals that the radiation eigenmodes (REMs) of a single ring selectively couple to specific guided modes of the fiber, depending on their symmetry. By tuning the physical parameters of the system, we demonstrate that the emission towards radiation modes can be highly suppressed, thereby enhancing the lifetime of the atomic excitation. Two identical rings positioned at a distance from each other along the nanofiber can exchange an excitation even at large separations through nanofiber guided modes. This results in enhanced sub-and super-radiance compared to the single-ring case. The selective coupling of REMs to specific guided modes and the enhanced sub-and super-radiance in a two-ring system suggest that the ring configuration is promising for implementing efficient and versatile light-matter nanofiber-based interfaces and achieving waveguide quantum electrodynamics (WQED).
