摘　　要：作为全光计算的基本逻辑单元的重要结构,全光开关的研究进展影响着整个全光计算甚至集成光学领域的发展。设计了一种硅基二氧化硅结构的超快全光开关,并通过双色抽运探测实验对光控光开关的消光比以及开关响应时间进行了测试,实现了开关强度比为7…1、开关时间约为500fs的超快全光开关的设计。As the basic structure of all-optical computing basic logic unit, the research progress of all-optical switch affects the development of all-optical computing and even the development of integrated optical field. An ultrafast all-optical switch with silicon-based silica structure is designed. The extinction ratio and the switch response time of the optically controlled optical switch are measured through two-color pump-probe experiment. The design of ultrafast all-optical switch with the switch intensity ratio of 7：1 and the switching time of 500 fs is realized.
