摘　　要：利用FP-SOA的增益特性曲线,实现了光分组交换中标签和净荷的分离,光功率均衡和TTL的功能．仿真结果表明:在分离标签和净荷的应用中,分别实现了对窄脉冲和宽脉冲的抑制比为10．5 dB和9 dB;在光功率均衡的应用中,实现了将10dB的功率动态范围减小到1．6dB;在TTL的应用中,实现了将6 dB功率差提升到14．5dB．In optical packet switching,three kinds of functions including the separation of label and payload, optical power equalization and Time to Live(TTL)are realized by using Fabry-Perot Semiconductor Optical Amplifier(FP-SOA).In the application of separating the label and payload,narrow pulses and wide pulses are suppressed to 10.5 dB and 9 dB,respectively.In the realization of damping the optical power,optical power variations are reduced from 10 dB to 1.6 dB.In the function of TTL,6 dB power extinction ratio ...
