Theoretical analysis of mechanism of photorefractive enhancement of photochromic gratings in BSO

We present the results of theoretical modelling of the increase in diffraction efficiency in photorefractive BSO under conditions of photorefractive enhancement via permanent photochromic gratings. The results are modelled using coupled wave theory, including the anisotropic nature of the secondary...

520 |a We present the results of theoretical modelling of the increase in diffraction efficiency in photorefractive BSO under conditions of photorefractive enhancement via permanent photochromic gratings. The results are modelled using coupled wave theory, including the anisotropic nature of the secondary refractive index grating, optical activity and electric field induced birefringence. The dependence of the enhancement of the diffraction efficiency as a function of the input polarisation of the diffracted beam. and of the applied electric field is presented for two different crystal geometries.
