中文摘要：

光纤色散特性是光纤通信系统的决定性因素．利用光学傅立叶变换（OFT）和变换受限（TL）脉冲可以实现色散的补偿，该色散补偿方案以傅立叶变换受限脉冲信号传输时的无畸变频谱为基础，在输出端利用光学傅立叶变换把这个无畸变的频谱转化成时域中的波形，这个波形和初始脉冲信号的波形在时域上是无失真变化的．然后用这个方案对三阶色散的补偿进行了分析研究，数值模拟结果和理论结果相符．

英文摘要：

The dispersive optical Fourier transformation （ characteristic of fiber is a key factor （OFT） and transform - limited （TL） for the fiber communication system. Using pulses can realize dispersion compensation, this scheme focuses on the unchanged spectrum of the Fourier transform -limited pulse after transmission, and at the output converts the unchanged spectrum to the time domain waveform using OFT, the transformed waveform in the time domain has no distortion. Then analyses the third -order dispersion compensation using this technique, the numerical simulation results agree well with the theory.
