光孤子通信 误码测量 超短光脉冲 外调制 optical soliton communication error measurement ultra-short optical pulse external modulation
摘要
进行了孤子通信的误码测量,成功地将2.5 Gbit/s的孤子传输了52 km,通过了2 h的测量无误码。对实验中的关键技术——超短光脉冲产生、高速外调制器、电信号和光信号的放大、光孤子脉冲序列与调制信号的同步以及正负色散位移光纤搭配技术进行了介绍和分析,对实验中的现象进行了理论分析。
Abstract
The error measurement for soliton communication is successfully realized. For 2.5 Gbit/s solitons transmitted over 52 km, there is no error within two hours. The key techniques——the generation of ultra-short optical pulses, external modulator with high speed, amplification for electrical and optical signals, the synchronization for soliton pulses and modulation signal and dispersion allocation for normal and abnormal dispersion fibers are introduced and analyzed. The experimental phenomena are theoretically analyzed.
