Gap soliton gating, dissociation, and retrieval via defect mode excitation in a resonant photonic crystal

Abstract

We consider the interaction within a bunch of two coherent optical pulses in a one dimensional, resonant photonic crystal which includes a defect produced by a coherent pump. Using numerical methods, the defect is shown to provide a selective reversible trap for a gap soliton mediated by the long-range coupling. This opens up new opportunities for signal transmission control and light localization.
