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.

Abstract

Abstract

Metallic nanowires supporting surface plasmon polaritons can localize optical fields at nanoscale for near-field imaging. In this paper, we propose a photonic-plasmonic probe for nanoscale light confinement. The linearly polarized fiber mode is asymmetrically coupled to radial plasmons to create hot-spot at the tip apex.
