Abstract

This article mainly introduces the role of MZM in practical communication systems, the materials used to make MZM modulators such as lithium niobate, and its working principle. It also explains why it changes due to environmental factors. This leads to the introduction of a method that controls the stable points of MZM by algorithmically controlling the voltage, and the algorithm is verified through experiments. Finally, a summary and outlook on the future development of MZM are provided.
