Abstract :
Quasi-static analysis of travelling-wave electrodes with asymmetrical finite thickness for electro-optic modulators is described. A generalised mode-matching method has been used to analyse the inhomogeneous structure with asymmetrical electrode thickness. The effects of asymmetrical electrode thickness on the effective dielectric constant and characteristic impedance of coplanar strip electrodes are discussed. Numerical computations show that asymmetrical properties of thick electrodes can improve the phase velocity mismatch between electric and optical waves in an electro-optical modulator or switch
