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.
