Instabilities of uniform states are ubiquitous processes occurring in a variety of spatially
extended nonlinear systems. These instabilities are at the heart of symmetry breaking …

In this study, the coupled nonlinear (1+ 1)-dimensional Drinfel'd–Sokolov–Wilson (DSW)
equation in dispersive water waves is investigated. The proposed structure is very important …

We report recent results obtained with a novel optical fiber experimental setup based on a
heterodyne optical time-domain reflectometer in the context of FPU recurrence process …

Liquid-core fibers offer local external control over pulse dispersion due to their strong
thermodynamic response, offering a new degree of freedom in accurate soliton steering for …

We theoretically and experimentally investigate the formation of dissipative coherent
structures in Kerr nonlinear optical microresonators, whose spectrum encompasses an …

Here, the concept of generating higher‐order dispersive waves (DWs) via quasi‐phase‐
matching (QPM) in periodically dispersion‐modulated liquid‐core fibers are demonstrated …

The dynamical Casimir effect is the generation of pairs of real particles or photons from the
vacuum as a result of a non-adiabatic change of a system parameter or boundary condition …

We present a theoretical and numerical study of light propagation in graded-index (GRIN)
multimode fibers where the core diameter has been periodically modulated along the …

We present a method with potential for fabricating freeform air-silica optical fibre preforms
which is free from the stacking constraints associated with conventional stack-and-draw. The …

Modulational instability in passive optical resonators, the triggering mechanism of frequency
comb and pulse train generation, is shown to exhibit transitions between regimes involving …
