| 摘 要： | LiNbO3晶体由于其透光范围广，响应速度快，不易潮解等特点而广泛用于高精度和高速光开关快门。为了将LiNbO3光开关曝光时间拓宽到纳秒领域从而弥补现有的高速光开关的不足，文章阐述了LiNbO3作为光开关理论原理，对多波段通光的晶体长宽比进行了优化设计，并对LiNbO3纳秒级光开关的可行性进行了实验验证。实验半波电压与理论符合很好，实验光信号和电信号在纳秒级范围内能实现同步响应。研究结果证实了LiNbO3光开关在纳秒级范围内的可行性，并为LiNbO3纳秒级光开关的制作提供了理论和实验依据。

| Abstract: | LiNbO3 crystal was widely used as high precision and high-speed switching shutters because of its features of wide wave band,fast response,non-easy deliquescence and so on.In order to expand exposure time of optical switching of LiNbO3 to nanosecond field so as to make up defects of extant high-speed optical switching,theoretical principles of LiNbO3 were explained as optical switching,and its aspect ratio for multi-band lights was optimized and the feasibility of LiNbo3 as a nanosecond optical switching was verified.Experimental half-wave voltages match theoretical values well.Experimental results also show that optical signal has synchronous response to electric signal.Results verify the feasibility of LiNbO3 as a nanosecond optical switching and provide theoretical and experimental foundations for the manufacturing of the optical switching. |
