| 为实现小于10ns光脉冲上升时间的超高速声光调制,本文提出一种光纤耦合声光调制器光脉冲时域响应的理论设计仿真方法。利用该方法对1064nm和1550nm工作波长光纤耦合声光调制器进行了仿真,结果预测器件的光脉冲上升时间分别为9.4ns和9.1ns；通过器件制作和测试验证,两个波长的器件实测光脉冲上升时间分别为9.74ns和9.22ns,实测与理论仿真结果偏差较小。文章最后对器件在超快光纤激光器种子源光脉冲选单、光纤水听阵列时分复用及潜在的宽带移频应用进行了介绍。 |

| To realize the ultra-high speed acousto-optic modulation of less than 10 nanosecond optical pulse rise time, this article proposes a theoretical method to simulate the optical pulse temporal response of fiber coupled acousto-optic modulator. Simulations are conducted for both 1064nm and 1550nm fiber coupled acousto-optic modulators, which predict the optical pulse rise time of devices are respectively 9.4ns and 9.1ns. Through devices fabricating and testing, the actual measured optical pulse rise time performances of the two devices are respectively 9.74ns and 9.22ns, and the deviations between results of actual measurement and theoretical simulation are small. At the end of the article, it introduces the devices’ applications in optical pulse picking for ultrafast fiber laser seed source, time division multiplexing of fiber-optic hydrophone arrays, and potential broadband frequency shifting. |
