摘要

提出了一种全光多电平同时抑制幅相噪声的再生器方案。对于由两个幅值和四个相位组成的星- 8qam信号，在高功率和低功率状态下，EVM降低分别为4 dB和2.5 dB。考虑了蓄热器性能的限制效应。

Multilevel amplitude and phase regeneration in a nonlinear amplifying loop mirror with a phase-sensitive amplifier

A novel regenerator scheme for all-optical multilevel simultaneous amplitude and phase noise suppression is proposed. For a star-8QAM signal, consisting of two amplitude and four phase states, EVM reduction is 4 dB and 2.5 dB for the high- and low-power states, respectively. The limiting effects of the regenerator performance have been considered.
