Resonant structures for band-operation optical modulators were investigated in this paper. Modulation efficiency was enhanced by the resonance of the modulating electrode. We can optimize the resonant structures by using equivalent circuit model and numerical electro-magnetic analysis such as the finite element method. The electric field distribution on the electrode was directly measured by the EO sampling technique.
