Journal ArticleDOI
Supercontinuum generation by stimulated Raman scattering and parametric four-wave mixing in photonic crystal fibers
Stéphane Coen,Alvin Hing Lun Chau,Rainer Leonhardt,John D. Harvey,Jonathan Knight,William J. Wadsworth,Philip St. J. Russell +6 more
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
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.
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.
Journal ArticleDOI
Extruded soft glass photonic crystal fiber for ultrabroad supercontinuum generation
V.V. Ravi Kanth Kumar,A.K. George,W.H. Reeves,Jonathan Knight,Philip St. J. Russell,Fiorenzo G. Omenetto,Antoinette J. Taylor +6 more
TL;DR: The fabrication and properties of soft glass photonic crystal fibers for supercontinuum generation have zero or anomalous group velocity dispersion at wavelengths around 1550 nm, and approximately an order of magnitude higher nonlinearity than attainable in comparable silica fibers.
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.
