title: Light propagation through a nonlinear defect: symmetry breaking and controlled soliton emission.
abstract: We investigate the emission of solitons at a nonlinear longitudinal defect. We discuss the basic physics and introduce a novel approach to achieve complete nonlinear control of the process. Theoretical results are confirmed by numerical simulations.
