摘要
利用注入锁模光纤激光器进行时钟提取实验,成功地从40 Gb/s伪随机码信号中提取出了40 GHz时钟信号。实验中,在注入信号进入环形腔之前先通过一个马赫曾德尔(M-Z)干涉仪,提高了注入信号中时钟频谱分量的相对大小,从而有利于时钟信号的提取。首先从10 Gb/s伪随机码信号中提取出波形很好的10 GHz时钟信号,并在此基础上从复用后的40 Gb/s伪随机码信号中提取出了40 GHz时钟信号。
Abstract
Clock extration experiment based on the injection mode-locking laser is conducted. 40 GHz optical clock pulses are extracted from 40 Gb/s pseudo-random codes using injection mode-locked fiber laser. In the experiment, the injection signals pass through a Mach-Zehnder (M-Z) interferometer before going into ring cavity, so that the clock component of the injection signals increases relatively and it is beneficial to clock recovery. 10 GHz clock signal with perfect waveform from 10 Gb/s pseudo-random code, and then 40 GHz clock signal is extracted is firstly obtained from 40 Gb/s pseudo-random code after multiplexing.
