摘要：
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.
