该文采用光纤声光调制器集成化、低功耗和热仿真设计技术, 设计并制作了工作波长1 550 nm、光脉冲上升时间16.7 ns、光脉冲延时抖动1.5 ns、电功耗0.72 W(脉冲) 、整体尺寸59.56 mm×49.48 mm×14.6 mm的高性能一体化光纤声光调制器。结果表明, 该调制器具有体积小及功耗低等优点, 对小型化低功耗光纤激光器、激光测风雷达及光纤分布式传感系统的研制有一定促进作用。

In this paper, a high performance integrated optical fiber acousto-optic modulator (FAMO) with operating wavelength of 1 550 nm, optical pulse rise time of 16.7 ns, optical pulse delay jitter of 1.5 ns, electric power consumption of 0.72 W(pulse operation mode) and overall size of 59.56 mm×49.48 mm×14.60 mm is designed and fabricated by using the integrated, low-power consumption and thermal simulation design technology of optical fiber acousto-optic modulator(FAOM). The modulator has the advantages of small size and low power consumption. It has a certain role in promoting the development of miniaturized low-power fiber lasers, laser wind radar and fiber-optic distributed sensing systems.
