论文摘要
开发了半古典7波模型，以研究退化双泵相敏感放大器的噪声性能。该方法通过多个四波混合过程来考虑到高阶波中注入的真空波动的传递。这种效应导致放大器的噪声图的降解相对于通常的3波模型预测的0 dB值。但是，事实证明，仔细选择纤维分散体可以使用高阶波来增强信号增益，而不会使噪声图降低到1 dB以上。
A semi-classical 7-wave model is developed to investigate the noise performances of a degenerate dual-pump phase sensitive amplifier. This approach takes into account the transfer to the signal, through multiple four-wave mixing processes, of the vacuum fluctuations injected in the high-order waves. This effect leads to a degradation of the noise figure of the amplifier with respect to the 0 dB value predicted by the usual 3-wave model. However, it is proved that a careful choice of the fiber dispersion allows to use the high-order waves to enhance the signal gain without degrading the noise figure above 1 dB.
