Abstract :
An adapted, simplified simulation tool based on the finite-difference method has been developed which is capable of analysing the high-frequency performance of lumped electroabsorption modulators with stacked dielectric and conductive materials. The impedance, transmission and reflection coefficients in addition to the electro-optical response of two different device layouts are simulated and compared to measurement results. Without any fit parameter, deviations do not exceed 1 dB for frequencies up to 25 GHz which allows detailed device optimisations.
