We study the simultaneous influence of optical activity, piezoelectric effect, and elasto-optic
effect on two-wave mixing (TWM) under diffusion recording in photorefractive Bi_12TiO_20 …

We solved numerically the set of partial, non-linear, material rate differential equations for
different values of grating period in a photorefractive, sillenite crystal (Bi12SiO20). These …

The energy exchange during two-wave mixing can be increased in photorefractive sillenite
crystals considering thick samples (ie, large interaction lengths). Nevertheless, in thick …

We study the influence of bias dc electric field on the optical properties of volume phase
gratings formed in optically active photorefractive sillenite crystals. By considering a general …

A methodology for the measurement of optical properties of photorefractive sillenite crystals
is presented. It allows to measure the spectral refractive index, absorption, optical activity …
