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

Liquid filling of photonic crystal fibres for grating writing
TL;DR: In this article, the authors showed that the grating index modulation of a grating written in germanium-doped photonic crystal fibre with 10 rings of holes was more than doubled for a fixed fluence.

High-energy few-cycle pulses: post-compression techniques
TL;DR: In this paper, post compression of short laser pulses was used to generate high energy few-cycle light pulses for ultrafast science. But this method is not suitable for high-energy few-cycled light pulses.

Tilted-front-interface chirped mirrors
TL;DR: In this paper, the front interface with respect to the internal interfaces of the multilayer is tilted to increase the bandwidth over which the dispersion of the mirrors can be controlled to a full optical octave, limited only by technological constraints.

Coupling characteristics between single-core fiber and multicore fiber.
Libo Yuan,Zhihai Liu,Jun Yang +2 more
TL;DR: An effective coupling approach is based on a process of standard splicing and tapering between the single-core single-mode fiber and the multicore single- mode fiber.

Accuracy of the capillary approximation for gas-filled kagomé-style photonic crystal fibers.
TL;DR: By introducing an empirical wavelength-dependent core radius, the range of validity of the capillary approximation is extended out to a wavelength of at least 0.98√(a(AP)t), independently of the gas-filling pressure.

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.
