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

A systematic analysis of parametric instabilities in nonlinear parabolic multimode fibers
Helena Lopez-Aviles,Fan O. Wu,Z. Sanjabi Eznaveh,M. A. Eftekhar,Frank W. Wise,R. Amezcua Correa,Demetrios N. Christodoulides +6 more
TL;DR: In this article, the authors provide a systematic analysis of geometric parametric instabilities in nonlinear graded-index multimode fibers and show that the resulting parametric problem takes the form of a Hill's equation that can be systematically addressed using a Floquet approach.

Designing dispersion-compensating photonic-crystal fibers using a genetic algorithm
TL;DR: In this paper, a genetic algorithm is combined with a fully vectorial finite-element solver to design photonic-crystal fibers (PCFs) for a broadband dispersion compensation in a generic stretcher-compressor system of an ytterbium fiber laser.

Designing of highly birefringence, dispersion shifted decagonal photonic crystal fiber with low confinement loss
TL;DR: In this article, a decagonal photonic crystal fiber (D-PCF) consisting unique cladding without structural complexity has been proposed, which has very high birefringent of the order of 10−2, less effective area of few square microns as well as low confinement loss of the scale of 10 −2 dB/m at 1.55μm 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.
