Temporal dynamics of spatially localized waves in quadratic nonlinear waveguide arrays

Setzpfandt, Frank; Solntsev, Alexander; Neshev, Dragomir; Pertsch, Thomas; Sohler, Wolfgang; Schiek, Roland


We study experimentally and theoretically the temporal dynamics of laser pulses propagating under conditions of spatial self-focusing in quadratic nonlinear waveguide arrays made from periodically poled lithium niobate. We observed temporal pulse breakup and temporal pulse narrowing and studied the dynamics of these effects in different waveguides. We investigated the influence of the frequency dependence of the mode indices as a limiting factor for soliton formation. Our experimental results...[Show more]
