Soliton-induced real-time planar waveguide and its guiding property in SBN:Cr crystal

One-dimensional (1D) bright screening optical solitons and the guiding properties of their induced planar waveguides are studied numerically and experimentally in SBN:Cr crystals. By employing the split-step beam propagation method and Petviashvili iteration method, 1D bright screening solitons are numerically simulated. By solving the guiding modes, the guiding properties of the soliton-induced planar waveguides are analyzed. Using a He-Ne laser at 633 nm as a soliton beam and a diode-pumped solid-state laser at 532 nm as a probe beam, experimental demonstrations are performed in a congruent SBN:Cr crystal. The experimental results coincide with the numerical ones. And it is shown that the waveguide structures induced by red soliton beams can be used as real-time waveguides.
