Mid‐infrared supercontinuum (mid‐IR SC) sources in the 2–20 µm molecular fingerprint
region are in high demand for a wide range of applications including optical coherence …

Pulse propagation in nonlinear waveguides is most frequently modeled by resorting to the
generalized nonlinear Schrödinger equation (GNLSE). In recent times, exciting new …

We propose an original, simple, and direct method to measure self-steepening (SS) in
nonlinear waveguides. Our proposal is based on results derived from the recently …

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 …

In this paper, we explore the formation of asymmetric modulation instability spectrum in the
metamaterials as a result of the joined effect of self-steepening and intra-pulse Raman …

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 …

We revisit the complex interplay between the Raman-induced frequency shift (RIFS) and the
effect of self-steepening (SS) in the propagation of solitons, and in the framework of 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 …

Supercontinuum (SC) generation towards the mid-infrared (MIR) range is an active field of
research and development motivated by a wide range of applications including optical …
