Broadband supercontinuum sources are of interest for various applications. The near- infrared region (1-3 μm) is specifically useful for biomedical diagnostics. One of the …
This review provides a detailed discussion of both the mathematical treatment and the impact of a frequency-dependent Kerr nonlinearity on the propagation of short pulses in …
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 …
We study supercontinuum (SC) generation in graphene-covered nanowires based on a generic model that correctly accounts for the evolution of the photon number under Kerr and …
We have recently introduced a new modeling equation for the propagation of pulses in optical waveguides, the photon-conserving Nonlinear Schrödinger Equation (pcNLSE) …
We study the interaction between an intense soliton and a weak control pulse in optical media with a zero-nonlinearity wavelength (ZNW). By means of numerical simulations, we …

The countless applications of ultrashort laser pulses in very different scientific areas explain the ongoing efforts to develop new strategies for the generation of light pulses with …
We derive a novel propagation equation for optical waveguides that properly accounts for two-photon absorption (TPA). We start from a simple quantum theory of nonlinear fibers …
We investigate the ultrafast nonlinear dynamics in a silica ringresonator composed of a silver-nanoparticle-doped core that exhibits rapidly varying frequency-dependent Kerr …
