Publication number: 20210211202Abstract: The present disclosure provides a dither-free bias control of an optical modulator (OM) for the externally-modulated transmitter with the silicon-based Mach-Zehnder modulator (MZM), while the nonlinear distortions (NLDs) are generated by the plasma dispersion effect of the silicon-based MZM. The present disclosure proposes to intentionally offset the bias point of the MZM from its quadrature points, and therefore the Mach-Zehnder interference (MZI)-induced even-order NLDs can be generated to cancel the plasma dispersion-induced even-order NLDs. In addition, the MZM bias control is also proposed to arbitrarily adjust and lock in the bias point of an OM so a transmitter with the integrated MZM may reach the best even-order NLDs by offsetting from the quadrature points. Moreover, while the proposed scheme could arbitrarily adjust and lock in the bias of MZM, the receiver sensitivity may be optimized by using such a bias control scheme to adjust the extinction ratio of multi-level signals.Type: ApplicationFiled: December 2, 2016Publication date: July 8, 2021Applicant: Oplink Communications, LLCInventors: Kuen-Ting TSAI, Zuon-Min CHUANG, Yao-Wen LIANG
