In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

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 …

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 investigate the polarization and electrical properties of additional light beams associated
with the generation of the spatial subharmonic K/2 of a fundamental photorefractive grating …

В работах [1–11] показано, что взаимодействие двух плоских световых пучков с
волновыми векторами k− 1 и k+ 1 на сформированной ими в фоторефрактивной среде …

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

We investigate experimentally and theoretically two-and four-wave mixing process in
photorefractive waveguide. Amplification and phase conjugation of the guided modes is …
