摘要

【目的】

常见的光开关通常偏振敏感或结构复杂，基于此，文章提出了一种2×2微流控光开关。

【方法】

文章所提光开关采用波导结构，利用基于磁流体的微流控驱动技术和微量的液体与空气，实现了光开关的光路选择和开关功能。文章同时还研究和讨论了光开关的光传输特性，并做出了结构优化。

【结果】

研究结果表明，2×2微流控光开关两个输出端口的插入损耗分别为0.42和0.20 dB，串扰分别为-24.13和-42.63 dB。

【结论】

文章所提2×2微流控光开关结构简单，对偏振不敏感，且比一般光开关的插入损耗和串扰小，可以作为构建光交叉连接（OXC）设备的交换核心，实现光网络的故障保护功能。

Abstract

【Objective】

Common optical switches are usually polarization sensitive or have complex structures

the article proposes a 2×2 microfluidic optical switch.

【Methods】

The optical switch proposed in this article employs a waveguide structure. It utilizes microfluidic driving technology based on magnetic fluids

along with trace amounts of liquid and air

to achieve optical path selection and switching functions for the optical switch. The transmission characteristics of optical switch are studied and discussed

and the structure of optical switch is optimized.

【Results】

The results show that the insertion losses at two output ports of optical switch are 0.42 and 0.20 dB

and the crosstalk are -24.13 and -42.63 dB

respectively.

【Conclusion】

The proposed 2×2 microfluidic optical switch has simple structure and is not sensitive to polarization. It also has lower insertion loss and crosstalk than common optical switches. It can be used as the switching core for building Optical Cross Connect (OXC) equipment to realize the fault protection function of the optical network.
