摘要
探讨了采用时间透镜来实现时间-频率间的傅里叶变换原理,给出了时间透镜的系统构成,设计了基于时间透镜的正交频分复用系统。仿真实验表明,基于时间透镜的高速光纤频域IM/DD传输系统,在传输速率大于10Gb/s时,比传统的IM/DD系统抗色散性能优势明显、性价比高且实用性强。
The paper discusses the principle of the time lens to achieve the time-inter-frequency Fourier trans- form and implementation, gives a diagram of the time lens andsystem design based on orthogonal frequency division multiplexing time lens. Simulation results show that the use of time-intensity modulation frequency Fourier transform structure ismore traditionallythanthe direct detection optical transmission systems, whenthe transmission rate is greater thanlOGb/s, the system has obvious advantages in anti-dispersion properties,and the system is cost-effective and practically.
