| 摘 要： | 用聚甲基丙烯酸甲酯(PMMA)和偶氮染料DRl以一定的比例混合，制成各向同性均匀薄膜样品。用经斩波器调制的线偏振氩离子激光(514nm，CW)作用样品产生光致双折射。作为探测光的线偏振氦氖激光(633nm，CW)经过样品，在与其原来偏振方向垂直的检偏器后的透射光强强度受控制光的调制作用，实现了光控光的全光开关效应。通过改变控制光的光功率及薄膜样品的温度。对样品的开关响应速度和开关调制深度进行了研究。在一定的实验条件下，用毫瓦量级的控制光功率实现了几个毫秒的开关响应速度和60％以上的开关调制深度。

| Abstract: | A simple all-optical switch based on the photoinduced birefringence is demonstrated in azodye (DR1) doped polymer (PMMA) thin film. The all optical switching effect of the sample is studied at different control beam modulating frequency, different control beam power and different temperature of the sample. In this paper, with the control beam power of milliwatt magnitude, response time in several milliseconds and the depth of modulation above 60% of the all optical switch are obtained. |
