We show that the nonlinear stage of the universal phenomenon of modulational instability,
and in particular its recurrent behavior, is deeply affected by arbitrarily weak losses. Indeed …

Recent studies have shown that light propagating in a nonlinear, highly multimode system
can thermalize in a manner totally analogous to that encountered in traditional statistical …

We show how the recurrence phenomenon characteristic of the nonlinear stage of induced
modulational instability in a passive fiber is affected by forcing. An additional linear …

We experimentally investigate higher-order seeded modulation instability in an optical fiber
experiment. The recirculating loop configuration with round trip losses compensation …

We address the fully nonlinear stage of seeded modulational instability in the Fermi-Pasta–
Ulam-Tsingou chain with quartic interaction potential (β-FPUT) subject to periodic boundary …

We extend the truncated three-wave theory used to describe degenerate four-wave mixing
in optical fibers to take into account the impact of higher-order harmonic sidebands. Using …

We study the interplay between intrinsic spin-orbit coupling and nonlinear photon-photon
interactions in a nonparaxial, elliptically polarized fluid of light propagating in a bulk Kerr …

A controlled version of the celebrated Fermi–Pasta–Ulam problem is introduced. The
feedback control algorithm based on Speed-gradient approach is proposed and analyzed …

In a two-core optical fiber (TCF), the linear coupling coefficient between the two cores in
general varies with the optical wavelength, a phenomenon known as coupling coefficient …

It is well known that the classic Fermi-Pasta-Ulam-Tsingou (FPUT) study of a chain of
nonlinear oscillators is closely related to a number of completely integrable systems …
