摘　　要：利用傅立叶变换,详细推导了光纤信号通过色散介质传播后输出的强度和相位的表达式.只要因色散而产生的附加场振幅足够小,该表达式对于任意的输入强度和相位都是有效的.Fourier transform algorithm is used to deduce the phase and intensity expressions of optical fiber signal after it is propagated through dispersion medium.They are valid for arbitrary input intensity and phase and,as long as the dispersion induced field amplitude is small compared with that of the input field.

关 键 词：傅立叶变换 色散光纤 光纤信号 强度 相位
