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

Experimental characterization of the deterministic interface states in two-dimensional photonic crystals
TL;DR: In this paper, a new type of deterministic interface states in two-dimensional photonic crystals is experimentally realized and characterized, where the existence of this type of interface states is solely dependent on the reflection properties of the bulk photonic crystal without any surface/interface decorations.

TL;DR: The use of a commercial table-top low-cost filament extruder is demonstrated to produce optical fibers with complex microstructure in a single step - from the pellets of the optical material directly to the final fiber.

Polarization coupling in a highly birefringent photonic crystal fiber by torsional acoustic wave
TL;DR: This work demonstrates and analyzes the acousto-optic coupling between two optical polarization modes of the LP(01) mode propagating in a highly birefringent photonic crystal fiber in an all-fiber tunable polarization filter configuration.

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.

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.
