为了在光信号处理中引入正负的概念,提出了偏振态旋转现象描述的光信号双极性乘法。以偏振光学的斯托克斯矢量法理论为基础,分析了半导体光放大器(SOA)的偏振旋转现象,从理论上提出了偏振旋转双极性乘法的概念。为了验证该理论,提出了一种实现双极性乘法器的实验方案,在实验系统中实现了两级SOA偏振旋转,其中第一级对光信号进行偏振编码,第二级完成双极性乘法。通过对乘法器输入不同排列组合的数据,验证了双极性乘法的4种情况,并给出了相关实验结果与分析,研究了双极性乘法器的原理和物理实现。
In order to introduce the concept of positive and negative in the optical signal processing, the bipolar multiplication of optical signal is proposed. Based on the theory of polarization-based Stokes vector theory, the polarization rotation of a semiconductor optical amplifier (SOA) is analyzed, and the concept of polarization rotation bipolar multiplication is theoretically proposed. In order to verify the theory, a bipolar multiplier experimental scheme is proposed. Two stages of SOA polarization rotation are realized in the experimental system. The first stage encodes the optical signal by polarization and the second stage completes bipolar multiplication . By inputting data of different permutations and combinations to the multiplier, four cases of bipolar multiplication are verified, and the related experimental results and analysis are given. The principle and physical implementation of the bipolar multiplier are studied.
