TLDR
In this paper, the optical properties of a photonic crystal fiber including a plurality of longitudinal holes are altered by virtue of the change in cross-sectional area of holes in that region.Abstract:
A photonic crystal fibre including a plurality of longitudinal holes (220), in which at least some of the holes have a different cross-sectional area in a first region (200) of the fibre, that region having been heat-treated after fabrication of the fibre, from their cross-sectional area in a second region of the fibre (190), wherein the optical properties of the fibre in the heat-treated region (200) are altered by virture of the change in cross-sectional area of holes (230) in that region (200).read more

Modeling and Analysis of Photonic Crystal Waveguides
TL;DR: In this article, a simple one-dimensional model for two-dimensional photonic crystal fibers (PCFs) is proposed, which is capable of predicting the normalized propagation constant, group-velocity dispersion, effective area, and leakage loss for PCFs of hexagonal lattice structure with a reasonable degree of accuracy when compared to published results that are based on numerical techniques.

Convection and radiation effects in hollow, compound optical fibers☆
TL;DR: In this article, a coupled model for the study of hollow, compound optical fiber drawing processes that accounts for the heat transfer in the preform and fiber and for the motion of the gases surrounding the preforms and fiber by means of two-dimensional equations was presented.
Journal ArticleDOI
Tunable Single-Polarization Single-Mode Microstructured Polymer Optical Fiber
TL;DR: In this paper, the selective polarization confinement loss mechanism is obtained by applying external hydrostatic pressure in a specially designed side-hole microstructured polymer optical fiber, and the possibility of tuning the single-polarization single-mode state with the input wavelength with fixed pressure or by introducing small changes in the inner ring of holes of the fiber cross section is presented.

Temperature-insensitive pressure transducer based on reflected broadened spectrum with enhanced sensitivity
TL;DR: In this article, half the grating of an FBG sensor on a natural rubber diaphragm was used to sense the pressure measurement, which resulted in bandwidth broadening and increased the sensitivity of the pressure transducer.

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.
Journal ArticleDOI
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.

Visible continuum generation in air–silica microstructure optical fibers with anomalous dispersion at 800 nm
TL;DR: In this article, the authors demonstrate experimentally that air-silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths, and exploit this feature to generate an optical continuum 550 THz in width, extending from the violet to the infrared.
