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 and numerical analysis of microstructured-core octagonal photonic crystal fiber for sensing applications
Kawsar Ahmed,Monir Morshed +1 more
TL;DR: In this article, an octagonal photonic crystal fiber (O-PCF) was proposed for liquid sensing, in which both core and cladding are microstructured, and some propagation characteristics of proposed structure have been investigated by using the full vectorial finite element method (FEM).
