在光通信网络中，光信号的强度波动是一个严重的问题，其由传输、放大和信号处理引起并由于传输、放大和信号处理而增长。由于光通信网络中光信号的强度波动会降低光信号的信噪比（SNR），最终导致数据的不准确，因此必须对光信号的强度波动进行补偿。为了补偿宽动态范围光脉冲的光强起伏，提出了一种基于光强相关谱型变化和光学模式识别的超快全光强度稳定器。为了验证所提出的方法，我们进行数值模拟和实验演示。通过实验验证了光强稳定器的基本工作原理。
In optical communication networks, an intensity fluctuation of optical signals is a serious issue, which is caused by and grows owing to transmission, amplification, and signal processing. Because it degrades the signal-to-noise ratio (SNR) of optical signals and eventually leads to inaccuracy of data, the intensity fluctuation of optical signals over optical communication networks must be compensated for. In order to compensate for the intensity fluctuation of optical pulses with a wide dynamic range, in this paper, we propose an ultrafast all-optical intensity stabilizer based on an intensity-dependent spectral pattern change and an optical pattern recognition. To verify the proposed method, we perform numerical simulations and experimental demonstrations. We confirm the basic operation of the optical intensity stabilizer through experimental demonstrations.
