All-optical switching in optically induced nonlinear waveguide couplers

Diebel, Falko; Leykam, Daniel; Boguslawski, Martin; Rose, Patrick; Denz, Cornelia; Desyatnikov, Anton S.


We experimentally demonstrate all-optical vortex switching in nonlinear coupled waveguide arrays optically induced in photorefractive media. Our technique is based on multiplexing of nondiffracting Bessel beams to induce various types of waveguide configurations. Using double- and quadruple-well potentials, we demonstrate precise control over the coupling strength between waveguides, the linear and nonlinear dynamics and symmetry-breaking bifurcations of guided light, and a power-controlled...[Show more]
