Journal ArticleDOI
Self-similar propagation and amplification of parabolic pulses in optical fibers.
TL;DR: Self-similarity analysis of the nonlinear Schrödinger equation with gain results in an exact asymptotic solution corresponding to a linearly chirped parabolic pulse which propagates self-similarly subject to simple scaling rules.
Journal ArticleDOI
Exact self-similar solutions of the generalized nonlinear Schrödinger equation with distributed coefficients.
TL;DR: A broad class of exact self-similar solutions to the nonlinear Schrödinger equation (NLSE) with distributed dispersion, nonlinearity, and gain or loss has been found and the stability of these solutions has been confirmed by numerical simulations of the NLSE.
Journal ArticleDOI
Supercontinuum generation by stimulated Raman scattering and parametric four-wave mixing in photonic crystal fibers

TL;DR: In this paper, an ultrabroadband octave-spanning white-light continuum is generated with 60-ps pump pulses of subkilowatt peak power, and the primary mechanism of spectral broadening is identified as the combined action of stimulated Raman scattering and parametric four-wave mixing.
Journal ArticleDOI
White-light supercontinuum generation with 60-ps pump pulses in a photonic crystal fiber
Stéphane Coen,Alvin Hing Lun Chau,Rainer Leonhardt,John D. Harvey,Jonathan Knight,William J. Wadsworth,Philip St. J. Russell +6 more
TL;DR: These findings demonstrate that ultrafast femtosecond pulses are not needed for efficient supercontinuum generation in photonic crystal fibers.
Journal ArticleDOI
Scalar modulation instability in the normal dispersion regime by use of a photonic crystal fiber.
John D. Harvey,Rainer Leonhardt,Stéphane Coen,Gordon K. L. Wong,Jonathan Knight,William J. Wadsworth,Philip St. J. Russell +6 more
TL;DR: Modulation instability at high frequencies has been demonstrated in the normal dispersion regime by use of a photonic crystal fiber that provides efficient conversion of red pump light into blue and near-infrared light.
