Abstract
In the theory of optical gap solitons, slowly-moving finite-amplitude Loren tzian solutions are found to mediate the transition from bright to coexiste nt dark-antidark solitary wave pairs when the laser frequency is detuned ou t of the proper edge of a dynamical photonic band gap. Catastrophe theory i s applied to give a geometrical description of this strongly asymmetrical " morphing" process.
