Beam Steering in Nonlocal Mediumwith Competing Nonlinearities
Nonlocal spatial solitons have potential applications in all-optical signal processing and optical interconnects due to their low power and particle-like nature on interactions. In order to obtain the effective methodto beam steering,the propagation of bright solitons and soliton pairs from the nonlocal medium to the nonlocal medium with competing nonlinearities is investigated by the numerical simulations. When propagate from nonlocalmedium to the nonlocal medium with competing nonlinearities,the nonlocal bright solitons will propagate in the form of breather,the nonlocal dipole solitons will split into two individual solitons,however,the propagation of thenonlocal oscillating bound state which is composed by two out-of-phase solitons depends on the position of the interface (nonlocal medium and nonlocal media with competing nonlinearities interface). When the position of the interface is choose at the node (the minimum distance of the soliton pairs),the nonlocal oscillating bound state will split into two individual solitons,otherwise,and the oscillating bound state will propagate in the form of bound state. These results introduce a new way to beam propagation and steering.
