Visible continuum generation in air–silica microstructure optical fibers with anomalous dispersion at 800 nm
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

Observation of extreme temporal events in CW-pumped supercontinuum
Arnaud Mussot,Alexandre Kudlinski,Mikhail I. Kolobov,Eric Louvergneaux,Marc Douay,Majid Taki +5 more
TL;DR: The temporal output of the supercontinuum is characterized by strong and brief power fluctuations, i.e. so-called optical rogue waves, and it is demonstrated numerically that these rare and strong events that appear and disappear from nowhere result from solitonic collisions.

Supercontinuum generation in chalcogenide-silica step-index fibers
N. Granzow,S. P. Stark,Markus A. Schmidt,Andrey Tverjanovich,Lothar Wondraczek,P. St. J. Russell +5 more
TL;DR: The pressure-assisted melt-filling approach makes it possible to realize highly nonlinear devices with unusual combinations of materials, and it is shown numerically that a 1 cm long As2S3:silica step-index fiber with a core diameter of 1 µm, pumped by 60 fs pulses at 1550 nm, would generate a broadband supercontinuum out to 4 µm.

High-power supercontinuum generation in highly nonlinear, dispersion-shifted fibers by use of a continuous-wave Raman fiber laser.
TL;DR: High-power supercontinua are demonstrated in highly nonlinear, dispersion-shifted fibers with a continuous-wave Raman fiber laser and the effect on continuum generation of parametric four-wave mixing coupled with the higher-order dispersion properties of the fiber is investigated.

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.

TL;DR: In this paper, the authors report measurements of frequency broadening due to self-phase modulation (SPM) in optical fibers, using single-mode silica-core fibers and mode-locked argon-laser pulses.

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.
