Impact of Low Frequency Laser Phase Noise in High Order Modulation Formats
Paper in proceeding, 2019

We present a simulation method and results for laser phase noise where we model the low frequency FM-Noise power spectral density (PSD) with a linear filter with Gaussian response. Several FM-Noise PSD are simulated and used in a back-to-back (B2B) transmission system where the performance of high order modulation formats is obtained in terms of bit error rate (BER) versus optical signal to noise ratio (OSNR). Our simulations results show that there is a cutoff region where the low frequency FM-Noise PSD starts introducing a penalty to the system. The simulations are performed by using a pilotbased carrier phase recovery with 16QAM, 64QAM and 256QAM modulation formats.
