We report two-wave mixing measurements in ion-implanted KNbO_3 planar waveguides
and their numerical analysis in the framework of a two-dimensional model that takes the …

We report on numerical simulations of two-wave mixing of Gaussian beams in
photorefractive materials. By using a model that takes the lateral intensity distribution of the …

We report what is to our knowledge the first observation and characterization of the
photorefractive effect in ion-implanted KNbO_3 waveguides. The implantation was …

Photorefractive wave mixing in a waveguide geometry with nonguided external pumps has

A nonlinear theory of two-beam coupling is formulated using the decoupled Kukhtarev
equations in the steady state to account for arbitrary pump-to-signal intensity ratios. The …

Nonlinear photorefractive wave mixing in waveguides provides unusual intermode coupling
effects which are independent of the overall light intensities. We present and demonstrate …

We present a new nondestructive method for measuring the propagation loss coefficient in
waveguides based on optimum end-fire coupling by self-pumped phase conjugation in a …
