Abstract. In several oxide crystals the refractive index can be changed by inhomogeneous
illumination, and these photorefractive properties have allowed for a wide variety of …

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 …

10.8 Conclusions and Outlook In this chapter, recent results on formation and investigation
of photorefractive waveguides have been summarized, and some interesting applications of …

We have demonstrated for the first time, to the best of our knowledge, photorefractive two-
wave mixing in He^+ implanted waveguides in one of the most promising materials for …

In a thin film planar geometry, the guiding effect due to the linear index results in light
confinement in the thin film layer, at the same time causing evanescent waves to decay into …

The formation dynamics of crossed-beam photorefractive gratings formed by the method of
two-center holographic recording in doubly doped LiNbO3 crystals is investigated in this …

Photorefractive crystals such as LiNbO3, KNbO3 or BaTiO3 are very promising for many
applications in all-optical signal processing. Unfortunately most photorefractive crystals …

Photorefractive effects in optical waveguides link two interesting research areas: First, light-
induced refractive index changes in optical materials, and second waveguide structures that …
