摘　　要：本文提出了一种由两个平行放置的正弦位相光栅构成的混合型多通道光学双稳性系统。理论上推导出了描述此系统的调制性和双稳性的数学模型。基于此模型,对不同参数情况下,此系统的调制性和双稳性进行了数字模拟。最后,对数字模拟结果进行了分析和总结.此系统有可能应用于光通信和光信息处理等领域。A grating multichannel optical bistable system is prosposed. In which, two parallely adjacently arranged sinusoidal phase gratings are used to form a multichannel optical modulator. The mathematical models, which describe the optical modulation of this modulator and the optical bistability of this optical bistable system are derived. The computer simulations on the optical modulation and bistability in a few order components of the diffracted light for various parameters are given. The discussion results based on the simulations are also presented. This system has some potential applications is optical communications and optical information processing.
