摘要 文章概述了激光器相位噪声对零差相干检测光通信系统性能的影响,对特定的基于平衡探测的科斯塔斯(Costas)环路接收系统相位误差进行了详细的理论分析,最后获得了不同传输码速率下的零差相干检测光通信系统对激光器线宽的具体要求。 This paper briefly describes the effect on the laser phase-noise to the optical homodyne coherent receiver. In theory, the detailed analysis of the phase-error with the specifically balanced Costas-type PLL receiver is given. Finally, the laser linewidth requirement about the optical homodyne coherent receiver is obtained at different bit rates.
