“…Many numerical analysis methods have been developed for the study of EO modulators, such as the finite-element, 4, 6 the finite difference, 7 the summary representation, 8 the formal mapping method, 9 and surface charge calculation. 10,11 Compared with other numerical analysis method, the surface charge method possesses special merits by itself: (1) No assumptions are required for the field behavior at large distances from the electrodes; (2) High computational accuracy can be achieved just using a limited number of discretization points. Therefore, the surface charge method is employed to model the transverse EO modulators with multilayer electrodes for its performance study.…”

For some electro-optic (EO) modulators, lowering the driving voltage is necessary to reduce the power consumption of the modulators. There are four significant factors influencing the driving voltage of the EO modulators: geometrical parameters of wafer and electrodes, surface and embedded electrodes, material properties of wafer, and structure of modulators. Using the superposition method and surface charge technique, the electric fields, halfwave voltages, switching times and optical transmissions of EO modulators with two-layer, three-layer, and four-layer electrodes are calculated, respectively. It is found that the halfwave voltage decreases while the switching time increase slightly as the number of layers increases. Such study demonstrates that using multilayer electrodes is an effective technique of lowering the halfwave voltage, which may have implication of EO modulator design

“…To analyze these transmission lines one has to find the capacitance and conductance matrices of the structure [1]. The capacitance matrix of lossless structures is determined using conformal mapping transformations [2,3], variational methods [4,5], spectral domain techniques [6,7], method of moments and green's function [8,9], analytically for certain particular geometries [10] and solving Laplace's equation [11][12][13]. Some ones solve Laplace's equation numerically, e.g., finite difference method [11] and some others analytically, e.g., fourier series or fourier integral method [12,13].…”

-This paper presents an efficient method, based on the transfer function simulation method, for the transient analysis of lossy and dispersive transmission lines terminated by nonlinear circuits. This method combines the efficiency provided by rational function approximation with the accuracy of using modal decomposition. For the task of computing the convolution integral, the transfer function simulation method was found to be more straightforward for implementation and more efficient than the recursive convolution method, thus providing further improvement in simulation efficiency. A robust and efficient method for the analysis of frequency dependent (dispersive) transmission lines is also reported. This method has been implemented in AS/X, IBM production circuit simulator, and has been used routinely for the analysis of practical lossy and dispersive coupled transmission lines.
