摘要
高速、高能效的光电（EO）开关对下一代数据通信系统至关重要。本文介绍了在铌酸锂 (LiNbO3) 平台上利用基于多模干扰 (MMI) 耦合器的新型 EO 交换机。该开关采用贝塞尔 S 弯波导设计，使弯曲损耗显著降低了 0.18 dB。这种贝塞尔弯曲 EO 开关在条形端口切换时的过量损耗为 0.33 dB，串扰为 -20.44 dB，而交叉端口切换时的过量损耗为 0.64 dB，串扰为 -13.66 dB。应用 3.27 V 电压可在三个输出之间实现 29:29:29 的平衡分光比。这种 EO 开关的长度为 4.09 mm，需要 4.1 V 的电压才能产生相移，电压效率为 1.68 V.cm。本文为新型环氧乙烷开关的设计提供了一条前景广阔的途径，并为下一代计算系统引入了更好的信号管理。
High-performance electro-optic switches with compact multimode interference and Bezier S-bend waveguides
High-speed and energy-efficient electro-optic (EO) switches are crucial for next-generation data communication systems. This paper presents a novel EO switch utilizing a multimode interference (MMI) coupler-based approach on a Lithium-Niobate (LiNbO3) platform. The switch is designed with Bezier S-bend waveguides, leading to a significant reduction in bending loss of 0.18 dB. This Bezier-bend EO switch shows an excess loss of 0.33 dB and crosstalk of -20.44 dB for the bar port switching, while the cross port switching exhibits an excess loss of 0.64 dB and crosstalk of -13.66 dB. Applying a 3.27 V voltage achieves a balanced splitting ratio of 29:29:29 between the three outputs. The length of this EO switch is 4.09 mm, which needs 4.1V to create a phase shift, showing a voltage efficiency of 1.68 V.cm. This paper presents a promising pathway for a novel EO switch design and introduces improved signal management for next-generation computing systems.
