摘要

给出了soa对光学32QAM的畸变和进一步再生的数值结果。由第一个SOA引起的扭曲被第二个装置作为饱和吸收器减少。10 Gbaud时EVM从36%降至16%，20 Gbaud时EVM从24%降至12% (Pin = -10.5 dBm)。结果表明，如果操作得当，这两个soa可以作为准线性放大器工作，因此可以用于采用多电平和/或相位编码光信号的中距离链路。

Distortion and regeneration of optical 32QAM by semiconductor optical amplifiers

Numerical results for distortion and further regeneration of optical 32QAM by SOAs are presented. The distortions caused by the first SOA were reduced by a second device acting as a saturable absorber. EVM is reduced from 36% to 16% for 10 Gbaud, and from 24% to 12% for 20 Gbaud (Pin = -10.5 dBm). It is demonstrated that the two SOAs, if properly operated, can work as a quasi-linear amplifier and so be eligible to be used in middle range links employing multilevel and/or phase encoded optical signal.
