Abstract

To meet the evolving demands of optical communication and optical signal processing, we propose a programmable optical filter based on a finite impulse response (FIR) structure, consisting of twelve amplitude tuning modules and phase tuning modules. The genetic algorithm is introduced to simultaneously manipulate the twelve electrodes, hence the proposed optical filter could obtain efficiently reconfigurable ability. The experimental results demonstrate that under the guidance of the genetic algorithm, the bandpass shape of the FIR filter could be tuned to a variety of waveforms. The fitting errors between the experimental and simulated curves are less than 4.5%. Especially, the passband ripples could be as low as 0.24 dB.

结合 FIR 结构和智能算法的可编程光学滤波器

为了满足光通信和光信号处理不断发展的需求，我们提出了一种基于有限脉冲响应（FIR）结构的可编程光滤波器，它由十二个振幅调谐模块和相位调谐模块组成。我们引入了遗传算法来同时操纵十二个电极，从而使所提出的光学滤波器获得高效的可重构能力。实验结果表明，在遗传算法的指导下，FIR 滤波器的带通形状可以根据各种波形进行调整。实验曲线与模拟曲线的拟合误差小于 4.5%。特别是，通带纹波可低至 0.24 dB。
