Abstract :
In this paper, methods of tunable Mach-Zehnder (MZ) modulator set-up in a Tunable Transmitter Assembly (TTA) have been investigated. Firstly the basic theory of the MZ modulator is introduced, and then there is discussion of MZ characterization in a Tunable Compact MZ modulator module (TCMZ). Secondly, dynamic control methods for accurately setting up the operating point for the MZ modulator during TTA AC test have been presented. Finally, detailed experiment results of a transmitter module with the method implemented have been analyzed. It demonstrates the methods improve application performance of the TTA.
