摘要
利用数值模拟方法分析了光纤Bragg光栅的结构参量对其频谱特性的影响,研究了旁瓣效应与κL值的关系,通过实验给出了第一、第二旁瓣的反射率与κL值的函数关系.实验测得频谱同理论模拟结果基本吻合,所得结论可为设计与制作高边模抑制比的光纤光栅提供参考依据.
By using numerical simulation method, fiber Bragg grating parameters＇ different effects on the grating＇s frequency spectum properties are studied in detail. The relation between side-petal domino effect and kL value is investigated. Then, the spectra obtained from experiments are analyzed, which are found to be in accordance with the theoretical results. The conclusion can he used for reference in the design of fiber Bragg gratings.
