Observation of linear and nonlinear strongly localized modes at phase-slip defects in one-dimensional photonic lattices.
We investigate light localization at a single phase-slip defect in one-dimensional photonic lattices, both numerically and experimentally. We demonstrate the existence of various robust linear and nonlinear localized modes in lithium niobate waveguide arrays exhibiting saturable defocusing nonlinearity.
