Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length. Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of important technological and scientific applications spanning many disciplines. The result has been a renaissance of interest in optical fibers and… 
Photonic Crystal Fibers
Photonic crystal fibers are a new class of optical fibers. Their artificial crystal-like microstructure results in a number of unusual properties. They can guide light not only through a well-known
Recent progress and novel applications of photonic crystal fibers
Photonic crystal fibers present a wavelength-scale periodic microstructure running along their length. Their core and two-dimensional photonic crystal might be based on varied geometries and
Enhanced nonlinear effects in photonic crystal fibers
Photonic crystal fibers are a new class of single-material optical fibers with wavelength-scale air holes running down the entire fiber length. Photonic crystal fibers were first developed in 1996
A new slant on photonic crystal fibers.
The comparison of the measured spectra with photonic band structure and Finite-Difference Time-Domain simulations provide strong evidence that the spectral features are a result of the periodic nature of the fiber microstructure in the transverse direction.
Photonic crystal fibres
Photonic crystal fibers exhibit physical features, from various angles, more versatile, intriguing and promising than those pertaining to the conventional optical fibers. Their cross-section can be
Hollow core photonic crystal fibers for beam delivery.
It is concluded that 7-unit-cell cores are currently most suitable for transmission of femtosecond and sub-picosecond pulses, whereas larger cores are better for delivering nanosecond pulsed and continuous-wave beams.
Tapered photonic crystal fibers.
This work demonstrates the tapering of a photonic crystal fiber to achieve a microstructure pitch of less than 300 nm and shows that the fundamental gap can be shifted down to the communications wavelengths, or even further to the visible spectrum.
Hollow-core photonic crystal fibers: progress and prospects
We review the progress made on the fabrication and applications of hollow-core photonic crystal fibres. The mechanism of the light guidance in these fibers is described along with their dispersion
Optical sensing with photonic crystal fibers
A review of optical fiber sensing demonstrations based on photonic crystal fibers is presented. The text is orga- nized in five main sections: the first three deal with sensing approaches relying on
Controlling Light-Matter Interactions using Photonic Crystal Fibers
The hollow microstructure of photonic crystal fiber permits low-loss single-mode guidance in both solid and hollow cores, opening up many opportunities for improved control of light-matter


Highly birefringent photonic crystal fibers.
Based on spectral measurements of the polarization mode beating, it is estimated that the strongly anisotropic photonic crystal fiber has a beat length of approximately 0.4 mm at a wavelength of 1540 nm, in good agreement with the results of modeling.
Endlessly single-mode photonic crystal fiber.
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.
Photonic band gap guidance in optical fibers
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. The

Single-Mode Photonic Band Gap Guidance of Light in Air.
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
