In this Letter, we present, for the first time, to the best of our knowledge, the modulation instability (MI) gain spectrum of waveguides with an arbitrary frequency-dependent …
The inclusion of self-steepening in the linear stability analysis of modulation instability (MI) leads to a power cutoff above which the MI gain vanishes. Under these conditions, MI in mid …
We propose an original, simple, and direct method for the simultaneous estimation of the self- steepening parameter and the fractional Raman contribution in fiber optics. Our proposal is …
We propose a novel and simple method for estimating the fractional Raman contribution, f_R, based on an analysis of a full model of modulation instability (MI) in waveguides. An …
Waveguides based on metamaterials may exhibit strongly frequency-dependent nonlinearities. In this work, we focus on the phenomenon of modulation instability in this type …
A well-known and thoroughly studied phenomenon in nonlinear wave propagation is that of modulation instability (MI). MI is usually approached as a perturbation to a pump, and its …
We show that, under certain conditions, modulation instability in nonlinear waveguides gives rise to the usual double-sideband spectral structure, but with a Raman gain profile. This …
