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

Supercontinuum generation and nonlinear pulse propagation in photonic crystal fiber: influence of the frequency-dependent effective mode area
TL;DR: In this article, the effect of the frequency dependence of the effective mode area in photonic crystal fiber on supercontinuum generation was quantified through a modified optical shock term and identified the major consequence as a reduction in the extreme long-wavelength edge of the super-continuum spectrum.

Generation of a broadband continuum by a Ti:sapphire femtosecond oscillator with a 1-GHz repetition rate.
Albrecht Bartels,Heinrich Kurz +1 more
TL;DR: A five-element Ti:sapphire femtosecond ring oscillator emitting a broadband continuum that ranges from 560 to 1150 nm at -50 dB below the maximum with a repetition rate of 1 GHz is demonstrated to make optical frequency metrology and future optical atomic clocks simpler and more stable.

Supercontinuum generation in submicrometer diameter silica fibers.
TL;DR: A strong diameter-dependence of the spectral broadening of the supercontinuum generated by femtosecond laser pulses in silica fiber tapers can be attributed to the fiber's diameter-dependent dispersion and nonlinearity.

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.
