Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by means of a simple geometrical

We show that 2D-decorated silicon nanowires exhibit a strong frequency dependence of the real (Kerr) and imaginary (two-photon absorption) nonlinear coefficients. In this setting, we demonstrate that the usual extension of the nonlinear Schrodinger e

We have recently introduced a new modeling equation for the propagation of pulses in optical waveguides, the photon-conserving Nonlinear Schrodinger Equation (pcNLSE) which, unlike the canonical NL...

We present a complete analytical description of saturable photoexcited-carrier (SPCR) based broadening in graphene-covered nanowires (GNs), providing physical insight on its dependence on input pulse power and chirp.

We present a model for supercontinuum generation correctly accounting for the photon number evolution under Kerr and TPA nonlinearities. The influence of graphene is treated within the framework of saturable photoexcited-carrier refraction.

We put forth a theoretical model allowing for the analysis of short-pulse interactions at time boundaries in waveguides with arbitrary frequency-dependent nonlinear profiles, in particular those exhibiting a zero-nonlinearity wavelength. Moreover, th

We study numerical solutions of the generalized nonlinear Schrödinger equation (GNLSE), focusing on the advantage of integrating the nonlinear part of the equation in the frequency domain (FD), rather than in the time domain (TD), when simulating s
