Paper Abstract

Combined the characteristics of Mach-Zehnder interferometer (MZI) with the advantages of microring resonator, a new and simple method for improving the performance of MZI electro-optic modulators (EOMs) is proposed. Using the coupled-mode theory and transfer matrix method, the transfer function of the device is analyzed and parameters are optimized. Numerical results demonstrate that Q-factor exceeding 1x104 and modulator bandwidth above 40Gbit/s is achieved by choosing the proper microring radius. And the 3rd-order nonlinear harmonic distortion of the modulator curve is cancelled and linear range higher than 90% is obtained by setting biasing point and choosing coupling coefficients. Compare with the single ring structure, performances of the designed device can be improved further by integrating multiple microring resonators.
