Abstract

We demonstrate ultrafast all-optical deflection of spatial solitons in an ${\mathrm{Al}}_x{\mathrm{Ga}}_{1-x}\mathrm{As}$ slab waveguide, using $190\mathrm{fs}$, $1550\mathrm{nm}$ pulses to generate and deflect the spatial soliton. The steering beam is focused onto the top of the waveguide near the soliton pathway, and the soliton is steered by refractive-index changes induced by optical Kerr, or free-carrier (Drude), effects. Angular deflections up to $8\mathrm{mrad}$ are observed.
