Nonlinear effect and thermal crosstalk effect are two major characteristics of silicon optical modulator different from the LiNbO3 modulator. This paper proposes a new automatic bias control method of 100G double polarization quadrature phase shift keying silicon optical modulator, including automatic bias control technology of nonlinear effect compensation method and thermal crosstalk effect compensation method. The experimental results show that the method can establish the linear relationship between bias voltage and phase of silicon optical modulator. This new technology is proved be feasible and practical by experiments.
Key words: coherent optical communication, silicon optical modulator, automatic bias control, nonlinear effect, thermal crosstalk effect.
