Zou Hui, Hu Yi, Tian Jun, et al. Stabilization control of the optimal bias point of M-Z external modulator[J]. 2008,(3):30-32. DOI: 10.13756/j.gtxyj.2008.03.004.
the merits of Mach-Zehnder external modulator for fiber-optic communications are first introduced and the importance of controlling the optimal bias point of M-Z external modulator explained.Then
its transfer function and curve are theoretically analyzed and the characteristics and control mechanism of the optimal bias point deduced.Finally
the control technique and realization of the optimal bias point are proposed and varified.
