摘要
全光纤保偏声光调制器(PAOM)是光传感和光通信系统的重要组成部分。理论分析了全光纤保偏声光调制器两正交偏振轴的光能量转换机理及耦合效率,讨论了在扭转声波作用下,两种全光纤保偏声光调制器的结构和调制原理。最后讨论了这种调制器在温度、应变及气体检测中的应用,并讨论了其优缺点。
The polarization all-fiber acoustooptic modulator（PAOM） is the key component for optical sensors and optical communication system.The transformation principle and coupling efficiency of optical energy transferred between two orthogonal polarization axes of PAOM are analyzed theoretically.The structure and modulation theory of two kinds of PAOMs,interacted with torsional acoustic wave,are discussed.The applications of this kind of modulator in sensing area are discussed.
