We report the formation of permanent two-dimensional waveguides in a bulk strontium barium niobate crystal. The waveguides are made by formation of a photorefractive spatial soliton in which the space-charge field induces ferroelectric domains that are permanently polarized opposite to the crystal axis. The fixed waveguide propagates light with 80% efficiency. These results make possible the permanent recording of intricate optical circuitry in the volume of a bulk crystal.
