Abstract

Tin thiohypodiphosphate (Sn₂P₂S₆) is a fast responding photorefractive material and very attractive for applications in parallel optical processing. Interband photorefractive gratings with response times in few tens of microseconds can be recorded in this material at wavelengths in the 500 nm region. This was used to demonstrate the feasibility of performing optical correlation at a 10 kHz frame rate using this effect. Recently we also characterized the values of the most important electro-optic coefficients in the monoclinic room temperature phase. Values reaching about 180 pm/V(r^T₁₁₁) at room temperature and about 5000 pm/V near the phase transition temperature T_c=64°C to the paraelectric phase were found. The photorefractive properties in the near infrared are also very interesting. An outlook of possible applications for wave manipulation in connection with infrared laser diodes will also be given.
