We demonstrate self-trapping of one-dimensional and two-dimensional optical beams in a photorefractive KNbO3 crystal. We study the waveguides induced by the self-trapped beams for prospective applications of tunable nonlinear frequency conversion in soliton-induced waveguides.

  16. For example, in SBN crystals we have found experimentally that a (2+1) D soliton can be launched (with the parameters of Ref. 10) in a direction that deviates by as much as ±8° from the crystalline a axis.

  20. Unfortunately, one of the b surfaces of our crystal is damaged, so we cannot investigate all possible alternatives in this normal-cut crystal.

  25. It has been brought to our attention that self-focusing effects (that may eventually lead to solitons) in photorefractive KNbO3 have also been (independently) demonstrated by R. Ryf, G.
