The space-charge field of the photorefractive grating in planar waveguides in cubic crystals is considered. Analytical expressions are derived from three cases: the initial stage of …
We investigate experimentally and theoretically two-and four-wave mixing process in photorefractive waveguide. Amplification and phase conjugation of the guided modes is …
