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

TL;DR: In this article, the optical dynamical Casimir effect was demonstrated in the near-infrared optical regime in a dispersion-oscillating photonic crystal fiber, based on the equivalence of the spatial modulation of the fiber core diameter to a pure temporal modulation when this is considered in the co-moving frame of the travelling pump pulse.

Magnetic fluid infiltrated dual core photonic crystal fiber based highly sensitive magnetic field sensor
Moutusi De,Vinod Kumar Singh +1 more
TL;DR: In this paper, a very high sensitive magnetic field sensor based on a square lattice dual core photonic crystal fiber (DCPCF) is proposed, which contains two big magnetic fluid (Fe3O4) infiltrated holes around the central region and they are forming two separate waveguide with mode coupling.

Temperature Compensated Strain Sensor Based on Cascaded Sagnac Interferometers and All-Solid Birefringent Hybrid Photonic Crystal Fibers
TL;DR: In this article, a temperature compensated strain sensor with two cascaded Sagnac interferometers is presented, which can suppress the crosstalk to a temperature upto 0.33 μe/°C, while still providing a high strain sensitivity of ~ 25.6 pm/μe.

A broadband ultra flattened chromatic dispersion microstructured fiber for optical communications
TL;DR: In this article, a double-cladding microstructured fiber (MF) is proposed, which is composed of elliptical air holes and silica, and the dependence of dispersion on the diameter of the air holes, the pitch and the axes of the elliptical holes is investigated numerically.

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.

TL;DR: The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.
