Paper Abstract

In this work we analyze the nonlinear evolution of mixed edge-screw phase dislocations and provide arguments on the existence of 1D dark spatial solitary waves of finite length in bulk Kerr nonlinear media. The characteristic phase gradients force the dark beam to steer in space. An all- optical switching scheme is proposed and critically evaluated with respect to stability and deflection control. Experimental results are reported on the decay of quasi-2D dark spatial solitons into finite-length 1D dark spatial solitons. The role of the saturation of the nonlinearity is discussed.
