Optical supermode dynamics are nowadays receiving an ever increasing attention in mode-division multiplexing applications. In this paper, we systematically analyze and characterize these modes in various structures based on coupled-mode theory. In pa

We show that the mode occupancies in nonlinear multimode optical systems follow a universal behavior that tends to maximize the system's entropy at steady-state. This thermodynamic response occurs irrespective of the type of nonlinearities involved.

We systematically study geometric parametric instabilities in parabolic multimode fibers. We show, both analytically and experimentally, that global dispersion processes and self-focusing effects can substantially affect the spectral positions and wi

We theoretically and experimentally demonstrate that the processes of multimode soliton fission and dispersive wave generation in parabolic-index multimode fibers, are substantially altered when the rate of intermodal nonlinear interactions is progre

We demonstrate that frequency generation in multimode parabolic-index fibers can be precisely engineered through appropriate fiber design. This is accomplished by exploiting the onset of a geometric parametric instability that arises from resonant sp
