Bifurcation of gap solitons through catastrophe theory
arXiv:physics/0104042 · doi:10.1103/PhysRevE.64.036617
Abstract
In the theory of optical gap solitons, slowly-moving finite-amplitude Lorentzian solutions are found to mediate the transition from bright to coexistent dark-antidark solitary wave pairs when the laser frequency is detuned out of the proper edge of a dynamical photonic bandgap. Catastrophe theory is applied to give a geometrical description of this strongly asymmetrical 'morphing' process.
