Abstract
Optical and photorefractive properties of reduced Rh-doped barium titanate are reported. Reduction eliminates energy levels of Rh+4 and Rh+5, and induces an absorption around 480 nm, which has a large light-induced transparency of ∼ 4 cm-1. After reduction, the speed increases by a factor of 30 though the electrooptic gain decreases by a factor of 1.6. In addition, it induces an increase of dark conductivity by three orders.
