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

Hollow-core photonic crystal fibres for delivery and compression of ultrashort optical pulses
TL;DR: In this article, the use of tapered hollow-core photonic crystal fibres for delivery and compression of ultrashort optical pulses is described, and the authors demonstrate delivery of transform-limited pulses with less than 100 fs pulse length and above 50 nJ energy through 8 m of fiber, in a single transverse mode.

Comparative study of photonic band gaps of germanium-based two-dimensional triangular-lattice and square-lattice and decagonal quasi-periodic photonic crystals
TL;DR: In this paper, Germanium-based two-dimensional (2D) triangular lattice and square-lattice and decagonal quasi-periodic photonic crystals (PCs) with the scatterer radius in the range of [0, 0.3a] and within two cases of the construction were calculated by using the plane wave expansion (PWE) method.
