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

Investigation of spontaneous Brillouin scattering generation based on non-adiabatic microfibres
TL;DR: In this paper, a non-adiabatic microfibre was used as the gain medium for spontaneous Brillouin scattering and gain bandwidth broadening due to its effect on irritation of the acoustic modes inside the micro-fibres.

Highly efficient wavelength-tunable anti-Stokes signal conversion by phase-matched four-wave mixing in the second-order mode of photonic crystal fiber
TL;DR: In this article, the authors used photonic crystal fiber (PCF) with zero dispersion wavelengths of the fundamental mode and the second-order mode at 985 nm and 885 nm designed and fabricated in their lab, the anti-Stokes signals from 586.5 to 558 nm are efficiently generated in the second order mode.

Self-switching of solitons in an AlGaAs nanowire coupler
TL;DR: It is demonstrated that an AlGaAs-nanowire-based coupler can be used as a useful soliton switching device at the telecommunication wavelength of 1550 nm and the linear loss and the self-steepening effect can be made insignificant with a judicious choice of the initial pulse width and operating wavelength.

Photonic crystal fiber with W-type effective refractive index profile
TL;DR: In this paper, the concept of W-type photonic crystal fiber (PCF) was proposed and a full-vector finite element method (FEM) was used to simulate the loss peak on the confinement loss curve.

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.

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.
