摘　　要：通常一种光开关只适用于一个特定的较窄领域。文章提出了一种基于介质上电润湿驱动技术的微流控矩阵光开关,可较广泛地应用于光通信和光电子系统中,并且结构简单、操作方便、偏振无关,易集成大型矩阵开关。文章给出了矩阵光开关的结构和工作原理,并设计了矩阵驱动电路。光开关的工作电压为58 V。研究结果表明:此矩阵光开关从“开”到“关”和从“关”到“开”的响应时间分别为120和100 ms;其插入损耗为0.26 dB,远比一般矩阵光开关低;消光比大,为139.7 dB。此外,文章给出了两种应用方案:光电显示器和多光束阵列开关。该课题的工作可为大型可集成矩阵光开关提供新的思路,并可促进微流控光学在光电子系统中的应用。Generally, an optical switch is only suitable for a narrow and particular field. In this paper, a microfluidic matrix optical switch based on the electrowetting-on-dielectric driving technology is proposed, which can be applied in a wide range of optical communication and optoelectronic systems. It has the advantages of simple structure, convenient operation, polarization independence and easy integration of large matrix switches. Here the structure and working principle of this matrix optical switch are given, and the matrix driving circuit is designed. The operating voltage of the optical switch is 58 V. The results show that the response time is 120 ms from "on" to "off" and is 100 ms from "off" to "on". The insertion loss is 0.26 dB, which is much lower than that of general matrix optical switches, and the extinction ratio is 139.7 dB. Moreover, two application schemes are given, namely, a photoelectricity display and a multi-beam array switch. Our work can provide a new idea for large-scale integrated matrix switches and promote the application of optofluidics in optoelectronic systems.
