Abstract :
We measure the parasitic four wave mixing tones generated by two signals that are amplified in two-pump fiber optical parametric amplifiers (2P-FOPAs). We consider two parametric amplifiers that use different lengths of fiber and pump powers but have identical parametric gain. We observe that the parasitic tones are stronger in the 2P-FOPA with longer fiber and smaller pump power. This is in agreement with our prediction of crosstalk in 2P-FOPAs.
