A Novel Nonlinearity Tolerant Super-Gaussian Distribution for Probabilistically Shaped Modulation

Abstract

Probabilistically-shaped constellations are found to have larger than expected Kerr nonlinearity induced penalty in long-haul transmission. In this paper, a novel nonlinear tolerant super-Gaussian distribution has been proposed which outperforms the Maxwell-Boltzmann distribution. The simulation and experimental results both show a significant improvement.
