摘要
根据对称金属包覆电光波导中本征损耗与古斯亨兴(Goos-Hnchen)位移的理论公式,导出了古斯亨兴位移与作用于波导两侧电压的二次关系公式。用622 μm厚度的四方相铌镁酸铅钛酸铅(PMN-PT)透明电光陶瓷片作为导波层制备了对称金属包覆波导,测量了古斯亨兴位移与作用于波导两侧电压的关系曲线,计算了所用透明电光陶瓷片的二次电光系数。实验结果与理论分析一致。
Abstract
The Goos-Hnchen shift at both sides of the waveguide is conducted, which gives rise to a quadric-curve relation between Goos-Hnchen shift and the applied voltage, based on the theoretical analysis of the intrinsic loss in a symmetrical metal-cladding electro-optic waveguide. A symmetrical metal-cladding waveguide is fabricated with a 622 μm-thick Pb(Mg1/3Nb2/3O3)-PbTiO3 (PMN-PT) transparent ceramic which serves as the guiding layer of the waveguide. Measurements of the relation between Goos-Hnchen shift and the applied voltage are carried out and the quadratic electro-optic coefficient of the PMN-PT ceramic is obtained. Experimental results are agreed well with the numerical simulations.
