A novel method for distortion-free optical pulse transmission is theoretically proposed and simulated, in which two time lenses formed by dispersion fibers and quadratic phase modulations are utilized. One is used as an optical inverse Fourier transformation (OIFT) device to transform the initial time-domain data to frequency-domain one at the transmitter and the other as an optical Fourier transformation (OFT) device to recover the data at the receiver. By using the unchanged spectral envelope in linear optical fiber communication, the initial data can be recovered. Through simulations, a 10\times100 Gb/s intensity-modulated direct-detection (IM-DD) dense wavelength division multiplexing (DWDM) system over 2000-km transmission without the compensation for polarization mode dispersion (PMD) and dispersion slope is achieved, which can be used to upgrade the current 10-Gb/s IM-DD system to a 100-Gb/s one directly.

分析并通过实验验证了光纤通信系统中偏振模色散引起的脉冲展宽对接收信号频谱的影响，在此基础上提出了一种偏振模色散的补偿技术。在10 Gbit/s的传输线路中实现了一阶偏振模色散（PMD）的自动补偿。
