Abstract

The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated. Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the presence of a full two-dimensional band gap in the photonic crystal cladding. Single-mode vacuum waveguides have a multitude of potential applications from ultrahigh-power transmission to the guiding of cold atoms.

摘要

已证明光可被限制在二氧化硅 - 空气光子晶体光纤的空心芯（一个大的气孔）内。只有特定的波长带被限制并沿光纤传导，每个波段对应光子晶体包层中完整二维带隙的存在。单模真空波导有许多潜在应用，从超高功率传输到冷原子的引导。
