Experimental Demonstration of Clock Component Extraction of NRZ Signal Using SOA Loop Mirror
基于SOA光纤环镜的NRZ信号时钟分量的提取

Clock component extraction of 2.5Gbit/s NRZ (non-return-to-zero) signal is demonstrated using SOA (semiconductor optical amplifier) loop mirror,in which the NRZ signal is converted to the corresponding PRZ (pseudo-return-to-zero) signal.The impact of SOA injection current and loop probe power on OSNR (optical signal-to-noise ratio) and ER (extinction ratio) of the converted output PRZ signal and loop transmittance is given and analyzed.
