Automatic Alignment for Integrated Photonic Devices Based on Genetic Algorithm

设计了一种基于遗传算法的集成光子器件自动对准方法.该算法克服了对准搜索中的早熟现象,改善了简单遗传算法搜索后期收敛速度慢的缺陷.仿真实验表明,在平面光波导与单模光纤自动对准过程中,该改进的遗传算法平均检测207个空间点时达到了0.01dB的对准功率损耗.

Automatic alignment technology for Integrated photonic devices based on Genetic algorithm was introduced,which solves premature convergence in automatic alignment and low precision of Simple Genetic algorithm in later searching.The simulation results indicate that the improved genetic algorithm can reach coupling loss 0.01 dB when platform moves 207 space points averagely.
