Opt Express. 2016 Feb 08;24(3):2774-87. doi: 10.1364/OE.24.002774.

Adopting an exact solution to four-wave mixing (FWM), wherein harmonic evolution is described by the sum of two Bessel functions, we identify two causes of amplitude to phase noise conversion which impair FWM saturation based amplitude regenerators: self-phase modulation...
