利用半导体光放大器增益饱和数学模型,第一次分析了基于单个半导体放大器进行光标签提取的节点性能.通过对半导体光放大器的参量分析和优化,仿真显示,对于标签速率2.5Gb/s、净荷速率40Gb/s的光分组包,提取的标签消光比可达到13dB.
In this paper, a novel scheme of header extraction for optical packet networks using only a semiconductor optical amplifier is proposed. Numerical analysis and simulation show, that more than 13 dB contrast ratio of the separated header at 2.5 Gb/s to the suppressed payload at 40 Gb/s could he achieved. In addition, the SOA parameters are discussed and designed to optimize the performance of the proposed scheme.
