Dispersive radiation and regime switching of oscillating bound solitons in twin-core fibers near zero-dispersion wavelength
arXiv:1705.04467 · doi:10.1103/PhysRevA.96.013809
Abstract
We study resonant radiation generated by bound solitons in a twin-core fiber near zero-dispersion wavelength, in the presence of higher order dispersion terms. We propose a theoretical description of dispersive wave generation mechanism and derive resonance conditions. The presence of third order dispersion term leads to generation of polychromatic dispersive radiation and transition from the regime of center of mass oscillations to the regime of amplitude oscillations. Such a transition is not reproduced in the case of symmetric fourth order dispersion.
