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 …

In recent times, materials exhibiting frequency-dependent optical nonlinearities, such as
nanoparticle-doped glasses and other metamaterials, have gathered significant interest. The …

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

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 present a quantum-mechanical model that describes fiber-based frequency conversion
by four-wave-mixing Bragg scattering in the presence of Raman interactions. In the case of …

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 …

The thesis is a research-oriented work that aims at expanding the knowledge of nonlinear
interaction between channels copropagating in the same optical fiber, classical and …
