TLDR
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.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 atomsread more

Design of Weakly Coupled Two-Mode Hollow-Core Antiresonant Fiber With Low Loss
TL;DR: Using numerical simulation, it is demonstrated that by tuning the glass sheets positions in cladding tubes the confinement losses (CLs) of higher-order modes (HOMs) can be maximized through core-cladding mode coupling.
