Photorefractive BaTiO(3) spheres and spherical disks.
We have produced single-crystal spheres and spherical disks of photorefractive barium titanate (BaTiO(3)) . The spheres and disks allow direct fiber-to-fiber two-beam coupling without additional optical elements. We also investigate the spontaneous oscillation of triangles and other whispering-gallery modes in these spherical structures.
