Journal ArticleDOI
Hollow-core photonic crystal fibres for gas-based nonlinear optics
TL;DR: In this article, nonlinear optical phenomena in gas-filled, hollow-core photonic crystal fibres that may lead to a new generation of versatile and efficient pulse-compression devices and gas-based light sources are discussed.
Journal ArticleDOI
Dissipative soliton resonances
TL;DR: In this paper, a dissipative soliton resonance was found for nonlinear dynamical systems governed by the complex cubic-quintic Ginzburg-Landau equation, where the soliton energy increases indefinitely.
Journal ArticleDOI
Ultrafast nonlinear optics in gas-filled hollow-core photonic crystal fibers [Invited]
TL;DR: In this article, the use of hollow-core photonic crystal fibers (PCFs) in the field of ultrafast gas-based nonlinear optics, including recent experiments, numerical modeling, and a discussion of future prospects, is discussed.

TL;DR: The concept of optical rogue wave was introduced by Solli et al. as discussed by the authors, who defined it as "an optical pulse whose amplitude or intensity is much higher than that of the surrounding pulses".

TL;DR: The spectral broadening of ~1 μJ 30 fs pulses propagating in an Ar-filled hollow-core photonic crystal fiber results in efficient emission of dispersive waves in the deep-UV region.
