摘　　要：基于铁电体畴反转结构的电光偏转特性,设计了一种片状集成的4×4电光开关,其由四个结构相同的半抛物和四个抛物形微小偏转器集成构成.通过优化抛物形偏转器结构,给出了电光开关的设计参量,电光开关性能通过光束传播法进行仿真模拟,仿真结果表明该开关切实可行.实际应用中,系统误差可以通过电场调节补偿,使光路准确交换.该片状电光开关的整体尺寸为48mm×2.2mm×0.5mm(长×宽×高),最大使用电场约13.73V/μm,适用于高速交换的光互连系统.An integrated 4×4 planar electro-optic switch is designed based on the electro-optic effect in ferroelectric inverted domains.It integrated four minute half-parabola shaped and four parabola shaped deflectors with the same configurations in a ferroelectric wafer.To optimize the design of the parabola shaped deflectors,an appropriate electro-optic switch is provided.Its properties of switch and exchange are analyzed using the beam propagation method(BPM).Simulation results show that the 4×4 planar electro-optic switch is feasible and the beam deflection errors can be compensated in practice by adjusting applied electric-field.The size of the optical switch is 48 mm×2.2 mm×0.5 mm and its maximum applied electric-field is about 13.73 V/μm.It has potential applications in high-speed optical exchange systems.
