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

Dissertation
Photonic crystal fibres and their applications in the nonlinear regime
TL;DR: In this paper, a method to reduce bend losses in all-solid photonic bandgap ''bres'' is presented, where the high-index inclusions in the cladding structure are redesigned to suppress cladding modes that strongly couple to the fundamental core-guided mode when the ''bre is bent.

TL;DR: Two types of international comparisons of femtosecond laser frequency combs have been performed in France and the USA and the conclusion that no systematic effects are present at this level is strengthened.

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.

Self-phase-modulation in silica optical fibers
Roger H. Stolen,Chinlon Lin +1 more
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.
Journal ArticleDOI
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.

Slab-coupled waveguides
TL;DR: The slab-coupled waveguide is a multidielectric waveguide that includes such special cases as the single-material fiber, the rib waveguide, and the strip-loaded film guide as mentioned in this paper.
