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

Tunable clover-shaped GaN photonic bandgap structures patterned by dual-step nanosphere lithography
K. H. Li,Zetao Ma,Hoi Wai Choi +2 more
TL;DR: In this article, the fabrication of close-packed clover-shaped photonic crystal structure on GaN by dual-step nanosphere lithography is demonstrated, by shrinkage of spheres prior to pattern transfer.

Bending analysis of a dual-core photonic crystal fiber
TL;DR: In this paper, a dual-core photonic crystal flber (DC-PCF) is proposed, and the bending characteristics of the DC-PCFs are investigated by injecting a broadband light into one flber core on one side and detecting output spectrum from another flbercore on the other side.

Design of Polarization Splitter via Liquid and Ti Infiltrated Photonic Crystal Fiber
TL;DR: In this article, a new polarization splitter based on Ti and liquid infiltrated photonic crystal fiber (PCF) with high birefringence was proposed, which offers an ultra short length of 83.9 μm, a high extinction ratio of −44.05 dB, and a coupling loss of 0.0068 dB and at 1.55 μm.

Design of large mode area all-solid anti-resonant fiber for high-power lasers
TL;DR: In this paper, the authors proposed an all-solid anti-resonant fiber (ARF) structure, which ensures single-mode operation in broadband by resonantly coupling higher-order modes into the cladding.

Reversible photo-induced long-period fiber gratings in photonic liquid crystal fibers
TL;DR: A novel light-controllable long-period fiber grating (LPFG) is demonstrated by making use of a PCF infiltrated with a photoresponsive liquid crystal (LC) mixture consisting of nematic LC molecules and light-sensitive 4-methoxyazobenzene (4MAB).

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.
