摘要
全光信号处理是高速光通信网络的一个关键技术。光头识别作为实现全光分组交换的关键技术之一,通过使用全光比较器可以实现。提出基于半导体光放大器马赫曾德尔干涉仪(SOA-MZI)级联结构的全光3 bit比较器,通过数值模拟对其进行了仿真研究,仿真速率为10 Gb/s。模拟结果显示输出信号质量良好,峰值功率超过7 mW,消光比为48 dB,脉冲半峰全宽为(FWHM)8.5 ps。输出脉冲具有较高的强度和稳定性。
Abstract
All-optical signal processing is a key technology in high speed optical communication network. The label/head processing as a key technology of optic packet smitching can be realized by using the all optical comparator. A 3-bit all optical comparator based on cascaded semiconductor optical amplifier-Mach-Zehnder interferometer (SOA-MZI) is demonstrated at 10 Gb/s by simulation. An extinction ratio of 48 dB and peak power values higher than 7 mW are found at the output. A fall width at half maximum (FWHM) of 8.5 ps is obtained for the output pulses from the comparator. The output pulses have a high intensity and a high stability.
