中文摘要：

基于光波时空二元性理论，研究了时间透镜和光脉冲在色散介质中传输的原理，提出了一种利用光脉冲频谱包络来传输光信号的方法：利用光脉冲的频谱包络在色散介质中保持不变的原理，在发射端用基于时间透镜的全光傅里叶逆变换器件将光脉冲的频谱包络转换到时域进行表示，从而得到新的传输符号；在接收端用基于时间透镜的全光傅里叶变换器件将原始光脉冲序列恢复。该传输系统可以消除色度色散、偏振模色散、时间抖动等线性畸变对光脉冲的影响。给出了全光傅里叶变换／逆变换器件的具体实现方法和10Gb／s-200km无预啁啾、无任何色散补偿的传输实验，验证了该方案的正确性与可行性，为高速光纤通信提供了一种新的方案。

英文摘要：

Based on optical wave space-time duality theory, time lens and principle of optical pulse transmission in dispersive media are studied. A method have been proposed using pulsesr spectral envelope to transmit optical signals. With the fact that pulses＇ spectral envelope will keep unchanged when propagating in dispersive medias, at the transmitter, an all-optical inverse Fourier transformation device based on time lens is used to transform the spectral envelope into time-domain, and a new transmitting symbol is obtained. An corresponding Fourier transformation device will be placed to recover original signals at the receiver. The transmission system presented can eliminate the chromatic dispersion, polarization mode dispersion （PMD）, timing jitter and other liner distortions. Detailed implementations of optical Fourier transformation and inverse Fourier transformation are given. Besides, a 10 Gb/s-200 km optical transmission experiment without any dispersion compensations or pre-chirp verifies our transmission scheme, which offers a new method in high-speed optical communications.
