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

Implications of theoretical analysis to explore the functional core dimension in one-rod core microstructured optical fibers
TL;DR: The functional core dimension for one-rod core triangular MOF (T-MOF) is estimated from its geometrical characteristics by using an alternative analytical field model to scrutinize the validity of the choice of effective core dimension (by adapting V-parameter, i.e., the normalized frequency).

Modulation instability induced supercontinuum generation in liquid core suspended photonic crystal fiber with cubic-quintic nonlinearities
TL;DR: In this paper, a liquid core suspended photonic crystal fiber (LCSPCF) was proposed as a potential waveguide structure for nonlinear applications, and the effect of suspension in the further enhancement of nonlinearity was highlighted.

All-silica single-mode optical fiber with photonic crystal cladding

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.
