Guiding of a one-dimensional optical beam with nanometer diameter

TLDR

The paper proposes the first concept of a one‑dimensional optical wave and its waveguides. The authors develop one‑dimensional optical waveguides that can guide nanometer‑diameter beams in the visible or near‑infrared, analyze their propagation theoretically, and discuss potential nanometer‑scale optical device applications. The study demonstrates that the proposed one‑dimensional optical waveguides are novel, newly named, and represent the first such waveguides.

Abstract

The concept of a one-dimensional optical wave and its waveguides are proposed for what is to our knowledge the first time. The proposed waveguides are principally new and named for one-dimensional optical waveguides. One-dimensional optical waveguides make it possible to guide very thin optical beams in the visible or the near-infrared region with a diameter in the nanometer range. The propagation properties are analyzed theoretically. The applications of the waveguides to optical devices in the nanometer range are discussed.
