摘　　要：该文介绍了一种全光纤耦合的单偏振声光调制器的设计及应用。理论分析了光纤声光调制器的工作原理,描述了单偏振光纤声光调制器的关键指标(插入损耗、消光比、光脉冲上升时间)的设计方法和单偏振光纤准直器的耦合工艺方法。设计制作了工作在1.06μm波长的高速低插损单偏振光纤声光调制器,其偏振消光比达到42 dB,能有效隔离系统偏振噪声。The design and application of an all-fiber coupled single polarization acousto-optic modulator is introduced in this paper.The working principle of the fiber acousto-optic modulatoris analyzed theoretically,and the design methods of the key indicators including insertion loss,extinction ratio,rise time of light pulse and the coupling process method of single polarization fiber collimatorsare presented.A single polarization fiber acousto-optic modulatorworking at a wavelength of 1.06μm with high speed and low insertion loss is designed and manufactured.The polarization extinction ratio(PER)reaches 42 dB,which effectively isolates the polarization noise of the system.
