Abstract
We demonstrate a photorefractive incoherent-to-coherent optical converter (PICOC) using anisotropic self-diffraction (ASD) in BaTiO3. Only two writing beams are required in the spatial light modulator and no extra readout beam is required. The diffraction efficiency reaches 50%. the resolution by using a thin crystal without expense of the diffraction efficiency because of the inherent high diffraction efficiency of ASD in BaTiO3.
