TLDR
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.Abstract:
We demonstrate experimentally for what is to our knowledge the first time that air–silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths. We exploit this feature to generate an optical continuum 550 THz in width, extending from the violet to the infrared, by propagating pulses of 100-fs duration and kilowatt peak powers through a microstructure fiber near the zero-dispersion wavelength.read more

Intensity and polarization dependences of the supercontinuum generation in birefringent and highly nonlinear microstructured fibers
TL;DR: Experimental results highlight the physica mechanism responsible for the initial spectral broadening of femtosecond Ti:Sapphire pulses in a highly birefringent microstructured fiber having a small effective area and bring clear evidences that the initial broadening mechanism leading to a broadband supercontinuum is indeed the fission of higher-order solitons into redshifted fundamental soliton along with blueshifted nonsolitonic radiation.

An Endlessly Single-Mode Photonic Crystal Fiber With Low Chromatic Dispersion, and Bend and Rotational Insensitivity
TL;DR: In this paper, a single-mode photonic crystal fiber (PCF) with low chromatic dispersion, low bend, and rotational sensitivity is presented, and the transverse electric field vector distributions of the fundamental, higher order and fundamental space filling modes, their effective indices, chromatic disersion, confinement, bending, and rotation losses are reported using full vector finite element method (FEM).

Supercontinuum generation in aqueous colloids containing silver nanoparticles.
TL;DR: The strong frequency dependence of the effective nonlinear coefficient of the composite significantly influences the spectral broadening by self-phase modulation and leads to a large blueshift of the spectra.

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.

Discovery of the soliton self-frequency shift.
TL;DR: The experimental discovery of a continuous shift in the optical frequency of a soliton pulse as it travels down the fiber is described, caused by a Raman self-pumping of the soliton.
