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

Ultrafast optical pulse delivery with fibers for nonlinear microscopy.
TL;DR: A variety of commonly used optical fibers are characterized in terms of how they affect pulse profile and imaging performance of nonlinear microscopy; the following parameters are quantified: spectral bandwidth and temporal pulse width, two‐photon excitation efficiency, and optical resolution.

Analysis of Kerr effect in resonator fiber optic gyros with triangular wave phase modulation
TL;DR: An in-depth analysis of the Kerr effect in resonator fiber optic gyros (R-FOGs) based on triangular wave phase modulation shows that the measurement error for an R-FOG with a hollow-core photonic bandgap fiber as the fiber loop can be one to two orders of magnitude smaller than a conventional single mode fiber loop.

Recent progress in photonic crystal fibres
TL;DR: The Holey photonic crystal fiber (PCF) as discussed by the authors consists of a thread of glass with microscopic air capillaries running along its length, and its many remarkable properties are overturning the basic precepts of textbook fiber technology.

A Fabrication Process for Microstructured Optical Fibers
TL;DR: In this paper, a fabrication process is introduced and demonstrated for a square microstructured optical fiber lattice and an existing mathematical model of the manufacturing process of a single-hole capillary tube was modified to identify parameters for the micro-structured fiber case.
Journal ArticleDOI
Polarization properties of rectangular lattice photonic crystal fibers
TL;DR: In this paper, the birefringence of photonic crystal fibers is analyzed by the plane wave expansion method applied to that of a single unit cell, which can be achieved by the reduction of the width and length ratio of rectangular lattice in the fibers.

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.
