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.
