摘要
在铌酸锂薄膜上设计并制作了一种用于电光模式切换的对称双模波导定向耦合器。本实验装置在2.5 V ~ 20 V的驱动电压范围内,可在C波段以高于65%的效率切换高阶模式。
Symmetric Two-Mode Waveguide Directional Coupler on Thin-Film Lithium Niobate for Electro-Optic Mode Switching
We design and fabricate a symmetric two-mode waveguide directional coupler on thin-film lithium niobite for electro-optic mode switching. Our experimental device can switch the higher-order mode with an efficiency higher than 65% in the C band with a driving voltage varying from 2.5 V to 20 V.
