摘　　要：研究了前向波与后向波在均匀光纤光栅内的动态特性。结果表明:前、后向波的振幅呈正弦震荡且震荡步调一致,极大值个数与波长阶数相同,极大值大小亦与波长阶数有关,而与在光栅中的位置无关,极大值周期分布于整个光栅长度;后向波振幅极小值为零。The dynamic properties of forward and backward waves in the fiber grating are studied. The results show that forward and backward waves amplitudes develope sinusoidally along the grating, the number of their amplitude maximums is equate to the corresponding rank of wavelength, their maximums are dependent of the wavelength rank and independent of their position in the grating, and their maximums distribute periodically along the grating;the minimum of backward wave amplitude is zero.
