Abstract
Abstract
We demonstrate the excitation of epsilon-near-zero (ENZ) resonance on a side-polished optical fiber nano-coated with aluminum-doped zinc oxide (AZO) with vanishing permittivity at near-infrared wavelength. The ENZ resonance is caused by the coupling between guided modes supported by optical fiber and the AZO nanolayer.

Abstract
Abstract
We derive an expression for electric-field intensity enhancement due to the epsilon-near-zero modes in ultra-thin conducting layers. We show that absorptance and field enhancement in aluminum-doped zinc oxide nanolayers grown by atomic layer deposition are controlled by nanolayer thickness and optical losses.
