在光纤参量放大器之后，作为波长转换器或在相敏模式中，由相位不敏感放大器（PIA）可以显著地减少宽带系统中信号之间的四波混频。我们推导出这两种混合配置的量子力学噪声系数（NF），并表明，添加PIA只会导致NF的适度增加。
Following a fiber optical parametric amplifier, used as a wavelength converter or in the phase-sensitive mode, by a phase-insensitive amplifier (PIA) can significantly reduce four-wave mixing between signals in broadband systems. We derive the quantum mechanical noise figures (NF) for these two hybrid configurations, and show that adding the PIA only leads to a moderate increase in NF.
