摘要
解释了利用法布里-珀罗(F-P)腔实现全光时钟恢复的原理。根据啁啾光栅(CFBG)的反射特性,从理论上分析了先利用CFBG对信号进行滤波再利用F-P腔进行时钟恢复在波长选择方面的优点,即将不需要恢复时钟的波长处的信号事先通过CFBG过滤掉。由于CFBG反射谱的顶端不平坦使得进入F-P腔的信号也不平坦,近而导致时钟恢复的效果不理想,故需利用切趾技术消除CFBG的反射谱顶端的不平坦,以获得更好的恢复效果。
Abstract
The principle of using the Fabry-Perot (F-P) cavity to achieve the all-optical clock recovery is explained. Based on the reflection characteristics of the chirped fiber Bragg grating (CFBG), the wavelength selection advantage of using the chirped fiber Bragg grating to filter the signals, before using the F-P cavity to achieve the all-optical clock recovery, is analyzed theoretically. which is that the signals at the wavelength that don't require the clock recovery are filtered out by the CFBG in advance. Due to the side lobes of the CFBG reflection spectrum, the effect of the filter is not quite good, and the quality of the all-optical clock recovery is bad. So the CFBG should be apodized to get a good quality of the all-optical clock recovery.
