摘要
设计了一种新的阵列对接方法,即将遗传算法导入光纤、光波导分支耦合器、光纤阵列的自动对接。数值仿真结果表明,常规的八通道波导分支耦合器的对接耦合能实现各通道小于9.1dB的插入损耗,最大值与最小值之差小于0.1dB,即自动对接方案具有良好的性能。
A new method for array alignment is designed, which is employed genetic algorithm in automatic alignment among fiber, Wavegnide splitter and fiber array. According the results of the mimic experiments, considering the 8 channels splitter, the insertion loss among these channels canbe controlled below 9.1dB, the max loss-min loss among the 8 channels is below 0.1dB. It shows that this method for array alignment has good capability.
