Paper Abstract

Two-beam coupling is observed in the planar Bi12TiO20/Bi12GeO20 waveguide in the presence of external square-wave field. The enhancement of the two-beam gain coefficient to the value of 0.77 cm-1 at (Lambda) equals 2.7 micrometer is achieved. The one level band transport model is extended for two-beam interaction in the waveguide in the presence of external field. From a set of experimental data, an acceptor density, an effective electro-optic coefficient, and a multiplication of carrier mobility and recombination time of the waveguide is estimated.
