Controllable Raman soliton self-frequency shift in nonlinear metamaterials

Soliton self-frequency shift: Self-similar solutions and their stability.

Ultrashort pulse propagation in fibers is affected by intrapulse Raman scattering (IRS) which causes both a linear frequency downshift and a quadratic displacement of the peak pulse, as functions of the propagation distance. This effect has been known and treated by perturbation methods applied to the nonlinear Schrödinger equation since the period of intense research on soliton propagation. He...

Soliton generation in active nonlinear metamaterials

We demonstrate experimentally a mechanism of the soliton generation in nonlinear active metamaterials. Our meta-structure consists of a ring resonator formed by a microwave amplifier loaded with a left-handed transmission line. We demonstrate a variety of nonlinear effects not described by weakly nonlinear models, and study experimentally the system’s spatiotemporal dynamics, including the gene...

Enhanced Soliton Self-Frequency Shift in a Longitudinally Varying Taper

Self-oscillations in nonlinear torsional metamaterials

We study the nonlinear dynamics of torsional meta-molecules—subwavelength resonators with strong coupling between electromagnetic excitation and rotational deformation—and show that such structures may undergo self-oscillations. We develop a semi-analytical model to evaluate the electromagnetic–elastic coupling in such structures. By analysing the local stability of the system, we reveal two di...
