Abstract

Various applications such as optical data processing or laser beam stearing have been developed using Bismuth Silicone Oxyde (Bi₁₂SiO₂₀) or Bismuth Germanium Oxyde (Bi₁₂GeO₂₀) However, much remains to be done to understand in which way the chemical composition and the structure of the crystals, changes their photorefractive behaviour. This is why our two labs developed on the one hand the growth of BGO crystals (with various chemical compositions, dopants and annealing conditions) and in the other hand, the optical determination of their photorefractive parameters.
