Abstract
A method and apparatus for reducing nonlinear phase noise that is induced in an optical transmission system by the interaction of optical amplifier noise and Kerr effect. The apparatus includes an intensity-scaled nonlinear phase noise compensator. The phase noise compensator reduces the nonlinear phase noise by applying a scaled differential signal strength estimate to estimated differential quadrature components or an estimated differential phase for providing a phase noise compensated representation.
