Near-infrared properties of Rh-doped Bi_(12)TiO_(20) crystals for photonic applications

摘要

The effect of Rh doping in Bi_(12)TiO_(20) (BTO) crystals on the photosensitivity and recording speed at 1064 nm is reported. Response time of 0.1 s is measured during real-time holographic recording without any preliminary treatments. Once the crystal is pre-excited with a green light, the detected response time becomes 0.02 s. A possibility to implement BTO:Rh crystal plate with liquid crystals into a hybrid organic/inorganic device is demonstrated, which opens perspectives for further near-infrared applications.
