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.

Finite-element analysis of birefringence and dispersion properties in actual and idealized holey-fiber structures

TL;DR: Through real-model simulations the polarization-dependent dispersion in actual fiber structures is numerically demonstrated, for the first time to the authors' knowledge, and the transverse-electric-field vector distributions in the fabricated holey fibers are clarified for the two linearly polarized fundamental modes.

TL;DR: In this paper, the modulational instability of continuous-wave backgrounds, and the related generation and evolution of deterministic rogue waves in the recently introduced parity?time system of linearly coupled nonlinear Schr?dinger equations, which describes a Kerr-nonlinear optical coupler with mutually balanced gain and loss in its cores.

Improving efficiency of supercontinuum generation in photonic crystal fibers by direct degenerate four-wave mixing

TL;DR: In this article, the authors numerically study supercontinuum generation in photonic crystal fibers pumped with low-power 30-ps pulses close to the zero dispersion wavelength, and show how the efficiency can be significantly improved by designing the dispersion to allow widely separated spectral lines generated by degenerate four-wave mixing directly from the pump to broaden and merge, resulting in a 800nm wide super-continuum.

Generation of broadband femtosecond visible pulses in dispersion-micromanaged holey fibers

TL;DR: Submillimeter-scale dispersion micromanagement is used to generate coherent and stable femtosecond visible pulses in holey fibers with various DMM designs to convert up to 20% of the total input energy to a low-noise solitary wave.

High brightness picosecond all-fiber generation in 525-1800nm range with picosecond Yb pumping.

TL;DR: Pumping of highly-nonlinear microstructured fibers with zero-dispersion around the pump wavelength of a 50kW peak-power picosecond Yb-fiber laser allowed extensive polychromatic picose Cond operation down to 525nm in all-fibre format.

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.

Self-phase-modulation in silica optical fibers

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.
