We demonstrated photorefractive time-domain differential phase detection method with Sb: Sn2P2S6 (SPS) which has very fast response speed. SPS crystal can improve the phase detection speed in holographic data storage than the other photorefractive material.
We demonstrated a dynamically reconfigurable optical waveguide based on a double phase conjugate mirror with a Sn2P2S6 crystal, which is applicable to future optical communication technologies such as three dimensional optical wiring and free space optics.
