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

Self-transformation of a powerful femtosecond laser pulse into a white-light laser pulse in bulk optical media (or supercontinuum generation)
V.P. Kandidov,Olga G. Kosareva,I.S. Golubtsov,Weiwei Liu,Andreas Becker,Neset Akozbek,Charles M. Bowden,See Leang Chin +7 more
TL;DR: In this article, it was shown that the high spatio-temporal localization of the light field in the filament, which enables the supercontinuum generation, is sustained due to the dynamic transformation of light field on the whole transverse scale of the beam, including its edges.

Polarization and dispersive properties of elliptical-hole photonic crystal fibers
TL;DR: In this article, the authors survey the properties of photonic crystal fibers with elliptical air holes, examining mode shapes, birefringence, group velocity walkoff and dispersion, and cutoff conditions.
Journal ArticleDOI
Nonlinear propagation and continuum generation in microstructured optical fibers
TL;DR: It is found that higher-order dispersion primarily determines the shape and width of the generated spectrum and that the fine spectral substructure exhibits extreme sensitivity to the initial pulse energy.

Soliton self-frequency shift in a short tapered air-silica microstructure fiber.
Xiang Liu,Chris Xu,Wayne H. Knox,Juhi Chandalia,Benjamin J. Eggleton,Sandra Greenberg Murray Hill Kosinski,Robert S. Windeler +6 more
TL;DR: In this article, the authors reported a self-frequency shift of more than 20% of the optical frequency in a tapered air-silica microstructure fiber that exhibits a widely flattened large anomalous dispersion in the near infrared.

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.
Journal ArticleDOI
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.
