Abstract
In this paper, a study of the influence and compensation of electroabsorption and Mach-Zehnder modulator non-linarites is made for the PAM-4, PAM-5 and PAM-8 modulation formats. The compensation is made with a level adjustment by a digital to analog converter (DAC) for which number of bits exceeds the minimal requirements for evaluated modulation schemes. As figures of merit, the level distribution and eye-opening corresponding to each level is used. The results show that compensation increases the signal quality by leveraging the modulator’s static extinction ratio.
