光纤参量放大器（FOPA）依赖于四波混频（FWM），因此提供了超低噪声系数的潜力，以及不受任何特定波长限制的大宽带增益。然而，尽管在FOPA内鼓励有效的FWM以获得放大，但是导致串扰的不想要的FWM同时发生。我们对FOPA中产生的FWM产品进行分类，评估不需要的FWM产品对FOPA性能的影响，并建议如何减轻这种影响。
Fibre optical parametric amplifiers (FOPA) rely on four-wave mixing (FWM) and therefore offer the potential for ultra-low noise figures as well as a large wideband gain unrestricted to any specific wavelength. However, whereas efficient FWM is encouraged within FOPA to obtain amplification, an unwanted FWM leading to crosstalk happens alongside. We classify products of FWM generated in FOPA, evaluate the impact of unwanted FWM products on FOPA performance and suggest how this impact can be mitigated.
