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

Temperature-Sensitive Photonic Liquid Crystal Fiber Modal Interferometer
TL;DR: In this article, an experimental investigation of the photonic crystal fiber (PCF) and photonic liquid crystal fiber modal interferometers is presented, where the PLCF interferometer is fabricated by infiltrating a liquid crystal (LC) into the PCF and then splicing the effective PCF between two singlemode fibers (SMF).

Supercontinuum generation through cascaded four-wave mixing in photonic-crystal fibers: When picoseconds do it better
TL;DR: By numerically solving the generalized nonlinear Schrodinger equation, the authors provides a comparative analysis of spectral and temporal transformations of pico and femtosecond laser pulses in a guided mode with a generic dispersion profile typical of a photonic-crystal fiber.

Surface-tension-driven Stokes flow
Peter Buchak,Darren Crowdy +1 more
TL;DR: A novel numerical scheme is presented for solving the problem of two dimensional Stokes flows with free boundaries whose evolution is driven by surface tension and is therefore tailored for the computation of multiple interacting free boundaries.

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.
