Abstract
The authors report on the photorefractive properties of cerium-doped strontium barium niobate (Ce:SBN60) single-crystal fibers grown by the laser-heated pedestal growth method. Single-crystal fibers, 250 mu m in diameter, were successfully grown along both the a- and c-axes. The diffraction efficiency and grating formation time results for each fiber in two beam coupling experiments are compared, with emphasis on their crystal orientation and relevant figure of merit. It is found that the hologram efficiency of the a-axis fiber is larger than that of the c-axis fiber and that its grating formation time is faster. The results suggest that Ce-doped SBN single-crystal fiber grown along the a-axis is a promising candidates for holographic storage, parallel data processing, and phase-conjugation mirrors.Keywords
