Because of its simplicity and high reflectivity, SPPC has a host of potential applications including correcting spatial phase distortion, and optical image processing. At the present time, SPPC has been realized in BaTiO<sub>3</sub>, KNbO<sub>3</sub>, Ce-doped SBN and KNSBN single crystals. The KNSBN展开更多
