We have studied two-wave mixing in a Ce-SBN crystal at different pump-to-signal ratios. A
small-signal gain coefficient as high as 15.9 cm/sup-1/at the 633 nm wavelength was …

A general perturbative approach to solving photorefractive material equations for a two-
wave mixing geometry is developed. The method allows the study of both stationary and …

El conocimiento del régimen no lineal, donde se generan las redes fotorrefractivas
armónicas está prácticamente limitado a un conocimiento aproximado del modelo de …

In the paraxial limit the photorefractive response of a cubic gyrotropic crystal with applied
square-wave electric field is considered for the symmetric incidence on a crystal of two plane …

This dissertation emphasizes on the realization, investigation and manipulation of Bragg
gratings with external electrical control especially for spectral filtering applications. Volume …

In our work we propose a novel method of analysis of photorefractive transport equations.
The method based on a perturbative approach can be used in the case of two wave mixing …

Adaptive RF interference reduction for broadband communication systems continues to be
problematic. The acousto-optic RF signal excision system offers real-time, narrowband RF …

The nonlinear properties of an integrated optical filter based on a photorefractive volume
holographic grating in LiNbO3 has been investigated. The spectral response of the filter has …
