【摘要】 用传输矩阵法对变迹相移光纤光栅的传输谱进行了分析,着重分析了相移点数、变迹函数的类型对光栅传输特性的影响。分析表明:可以通过改变光栅的相移点数、选择不同的变迹函数,研制用于WDM和DWDM的滤波器。更多还原

【Abstract】 The characteristics of apodized and phase-shifted fiber Bragg grating are analyzed by means of transfer matrix formulation. The impact of inserted phase-number and apodising functions on transmission characteristics have been discussed. The results show that a series of band pass filter applied in WDM and DWDM were made by the change of inserted phase-number and apodising functions.更多还原
