Nonlinear pulse transformation and phase transitions in LiNbO3 waveguide arrays

Setzpfandt, Frank; Neshev, Dragomir; Schiek, Roland; Solntsev, Alexander; Pertsch, Thomas; Sukhorukov, Andrey; Kivshar, Yuri


Lithium niobate waveguide arrays (WGAs) [1] offer rich possibilities for all-optical shaping, switching, and routing of short optical pulses. In such systems, light from the fundamental wave (FW) is coupled by the2 nonlinearity to the second harmonic (SH) giving rise to a strong cascaded quadratic nonlinearity. Recently a new type of phase transition in the nonlinear localised states was identified due to the competition between self-focusing and SH waveguide coupling, where the SH phase...[Show more]
