Soliton control in tunable optical lattices

This study presents an overview of recent theoretical results on soliton steering and switching in photonic lattices with an emphasis on new features afforded by the lattice tunability. This investigation discusses the impact of lattice depth on the mobility of one-dimensional solitons in local and nonlocal nonlinear media, as well as the possibility to pack, transfer, and extract single lattice solitons from complex stable trains and bound soliton states. This work also describes complex guiding structures that can be built with several coherent or incoherent Bessel beams, vorticityless or carrying phase dislocations. Results on soliton spiraling in dynamical rotating Bessel lattices created with several collinear Bessel beams carrying phase dislocations are presented as well
