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

A source of optical supercontinuum radiation
TL;DR: In this article, a source of optical supercontinuum radiation for generating blue-enhanced spectral components using a pump wavelength of substantially 1064 nm is described, consisting of a microstructured optical fiber and a pump laser arranged to generate lasing radiation at the pump wavelength.

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.

Group-velocity dispersion in photonic crystal fibers.
TL;DR: The dispersion properties of photonic crystal fibers are calculated by expression of the modal field as a sum of localized orthogonal functions to derive uniform dispersion values for single mode and double mode fibers.
