我们利用激光辐照制备了BaO-TiO2GeO2-SiO2基定向空间选择晶化结构的玻璃光纤，并基于二阶光学非线性研究了电光双折射变化引起的可变光衰减。偏振信号的透射率由施加在光纤上的电场控制，电光光纤器件以极低的纳瓦电力损耗运行。
We have fabricated BaO-TiO2-GeO2-SiO2-based glass fibers with the oriented space-selectively crystallized structure by laser irradiation and also demonstrated variable optical attenuation induced by electro-optical birefringence change based on second-order optical nonlinearity. The transmittance of a polarized signal is controlled by an electric field applied to the fiber, and the electro-optic fiber devices are operated with extremely low nanowatt electric power dissipation.
