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

Bacteriorhodopsin: a natural, efficient (nonlinear) photonic crystal
TL;DR: In this paper, the disappearance of the angular dependence of the nonlinear scattering is shown to be a consequence of the solubilization of the large purple membrane patches into individual protein monomers.

Chirped multilayer hollow waveguides with broadband transmission
A. Husakov,J. Herrmann +1 more
TL;DR: In this article, a genetic algorithm was used to optimize the layer thickness of a hollow waveguide with a multilayer dielectric cladding, and it was shown that in such "chirped" waveguide low loss over a wavelength range with more than one octave width can be achieved.

Design of polarization-preserving photonic crystal fibres with elliptical pores
TL;DR: In this paper, a microstructure of air capillaries with an elliptical cross section in a tread of glass is discussed, which gives an opportunity for the creation of a polarization-preserving fibre with very small beat length between the fundamental modes of different polarization.

Cheng Ma,Yingnan Jiang,Yang Xudong,Chuanxi Wang,Hui Li,Fengxia Dong,Bai Yang,Kui Yu,Quan Lin +8 more
TL;DR: The PS-co-PDMAA opal hydrogels could be a practical system for diffraction-based detections and was particularly sensitive to the presence of thiocyanate (SCN(-)) ions.

All-silica single-mode optical fiber with photonic crystal cladding
TL;DR: The fabrication of a new type of optical waveguide: the photonic crystal fiber that supports a single robust low-loss guided mode over a very broad spectral range of at least 458-1550 nm.

Endlessly single-mode photonic crystal fiber.
TL;DR: An effective-index model confirms that an all-silica optical fiber made by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes can be single mode for any wavelength.

Hollow metallic and dielectric waveguides for long distance optical transmission and lasers
TL;DR: In this paper, the field configurations and propagation constants of a hollow circular waveguide made of dielectric material or metal for application as an optical waveguide were determined and the increase of attenuation due to curvature of the axis was also determined.

Photonic Band Gap Guidance in Optical Fibers
TL;DR: A fundamentally different type of optical waveguide structure is demonstrated, in which light is confined to the vicinity of a low-index region by a two-dimensional photonic band gap crystal.

Full 2-D photonic bandgaps in silica/air structures
TL;DR: In this paper, full 2D photonic bandgaps are demonstrated for all polarisations in structures with refractive index contrast as small as that of silica and air, and a new type of optical fiber based on these structures is proposed.
