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

Frequency-tunable supercontinuum generation in photonic-crystal fibers by femtosecond pulses of an optical parametric amplifier
Andrei B. Fedotov,A. N. Naumov,Aleksei M. Zheltikov,Ignac Bugar,Dusan Chorvat,Alexander Tarasevitch,Dietrich von der Linde +6 more
TL;DR: In this article, the role of dispersion in spectral broadening and supercontinuum generation was discussed, and it was shown that decreasing the size of the fiber core allowed the efficiency of supercontinuity generation to be improved without increasing the laser intensity.
