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

Effects of a seed pulse on rogue-wave formation for midinfrared supercontinuum generation in chalcogenide photonic crystal fibers
TL;DR: In this article, an approach based on seed-induced modulation instability is used to regulate the formation of optical rogue waves (RWs) in mid-infrared supercontinuum (MIR-SC) generation with a femtosecond pump in the anomalous dispersion regime of a chalcogenide photonic crystal fiber.

TL;DR: In this paper, a train of femtosecond pulses generated by a mode-locked Ti:sapphire laser into the fundamental mode of a photonic crystal fiber with central holes fabricated in the lab was used to generate flat supercontinuum in the telecommunication wave bands of E+S+C.

Large area photonic crystal cavities: a local density approach.
TL;DR: A local density approach is used to capture the effect of both ideal and distorted photonic crystals in an effective mass and an effective potential and uses these to map the problem of calculating the electromagnetic field modes to solving a simple time-independent Schrödinger equation.

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.
