Research of a nanosecond optical switching with LiNbO3 crystal
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高速光开关的不足,阐述了LiNbO3作为光开关的理论原理, 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.
