In order to achieve broadband modulation of electrooptic intensity modulators, design optimization is very important. A thorough understanding of the characteristics of the electrode structure permits parameter optimization in the design of electrooptic modulators. In this paper, calculations of the electric field distribution, impedance, the effective index for microwaves are presented using the Fourier-series method1 for a quasi-static analysis of coplanar waveguide (CPW). Using this approach, the design optimization will also be discussed.
