Generation of dark multisoliton complexes in a magnonic ring resonator with dispersion management and competing nonlinear spin-wave interactions

Abstract: Multisoliton complexes have been generated in an active ring resonator with an L-shaped magnonic microwaveguide and a saturated amplifier. It has been shown that an irregular microwaveguide simultaneously supports both the propagation of magnetostatic spin waves with different (normal and anomalous) dispersion and competition between three- and four-wave spin-wave interactions. Generated multisoliton complexes consist of quasiperiodic sequences of two dark parametric pulses containing “soliton trains” consisting of three dark ultrashort four-wave envelope solitons. It has been found that quasiperiodic sequences of multisoliton complexes generated by the active ring resonator with a regular magnonic microwaveguide consist of one dark parametric pulse, which also contains three dark four-wave solitons. However, in contrast to the preceding case, four-wave solitons, having a longer duration, do not form soliton trains inside a dark parametric pulse.
