| 摘 要： | 为了解决常见光调制器偏振依赖或结构复杂的问题，本文基于微流控光学提出一种可控光脉冲调制器。利用基于T形结产生的离散液滴和全反射原理的微流控光开关，将连续光变换成数字脉冲信号，并通过调节液滴的长度和生成速率调制光脉冲的宽度和频率。所提微流控光脉冲调制器具有结构简单、插入损耗低、消光比高、易集成的优点。微流控光脉冲调制器的流场与光场特性被分析，结构被优化。研究结果显示：该光脉冲调制器的消光比为17.74 dB,插入损耗为0.49 dB。

| Abstract: | To address the polarization dependence or complex structure of common optical modulators,this paper proposes a controllable optical pulse modulator based on optofluidics.The continuous light is converted into digital pulse signal by using a microfluidic optical switch,which based on the discrete droplets generated by T-junction and the principle of total internal reflection,and the width and frequency of the optical pulse can be modulated by adjusting the length and generation rate of the droplets.The proposed microfluidic optical pulse modulator has the advantages of simple structure,low insertion loss,high extinction ratio and easy integration.The flow field and optical field characteristics of the microfluidic optical pulse modulator are analyzed and its structure is optimized. The results show that the extinction ratio of the optical pulse modulator is 17.74 dB and the insertion loss is 0.49 dB. |
