Ruthenium and Rhodium doped sillenite crystals: holographic properties and applications at near-infrared spectral range

We report an improvement of the response time and near infrared sensitivity of sillenite crystals Bi12SiO20 (BSO), Bi12TiO20 (BTO) doped with transition metal ions as Ru and Rh. Real-time holographic recording is performed at 1064 nm at a diffusion regime. By using 532 nm light for pre-excitation, significant operation speed of 20 ms is achieved in case of Rh-doped BTO crystal. Further, a possibility to combine doped sillenite plates with liquid crystal into a organic/inorganic hybrid devices (Liquid Crystal Light Valves) is demonstrated, which opens many prospects for further near infrared photonic applications.
