10 GHz optoelectronic 振荡器(OEO ) 的试验性的优化基于直接调制的 1.55 m 散布了反馈(DFB ) 激光在这份报纸被表明。直接调制的激光(数据管理语言) 的阶段噪音基于 OEO 被激光偏爱水流的合适的选择显著地减少,由使用,分散作为一根延期线转移了纤维。在优化以后完成的 DML OEO 的阶段噪音表演接近用商业 DFB 激光和一个 LiNbO3 Mach-Zehnder 调节的人构造的常规 OEO 的。基于的 OEO 最与在半导体底层上综合的部件为缩小的 OEO 体系结构的未来实现正在答应的数据管理语言。
The experimental optimization of a 10 GHz optoelectronic oscillator (OEO) based on a 1.55μm directly modulated distributed feedback (DFB) laser is demonstrated in this paper. The phase noise of the directly modulated laser (DML) based OEO is signifi- cantly reduced by proper selection of the laser's bias current and by using a dispersion shifted fiber as a delay line. The phase noise performance of the DML OEO achieved after optimization is close to that of a conventional OEO constructed using a com- mercial DFB laser and a LiNbO3 Mach-Zebnder modulator. The DML based OEO is most promising for future realization of a miniature OEO architecture with the components integrated on a semiconductor substrate.
