چکیده
Please cite this article in press as: S. Wabnitz, N We show that inducing modulation instability with a weak modulation whose frequency is such that its second harmonic falls within the band of instability may lead to asynchronous Fermi–Pasta–Ulam recurrence and efficient transfer of power from the pump into the second harmonic of the modulation, resulting in a periodic modulation at the second harmonic with extinction ratios in excess of 30 dB. 2009 Elsevier B.V.

Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...
متن کاملInfluence of the pump shape on the modulation instability process induced in a dispersion oscillating fiber
We show that taking into account the temporal intensity profile of a pulsed pump beam may lead to significant deviations from the predictions based on a continuous wave analysis of the modulation instability process occurring in a dispersion oscillating fiber operating under the conditions that lead to gain sideband splitting. Potential application to a pulse doubling scheme with tunable delay ...
متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...
