Summary :

By using electro-optic sampling technique, the electric field distribution on a resonant electrode for optical modulation was measured with a resolution in the micrometer range, while the range of measurement area was a few millimeters. The electric field on the asymmetric resonant electrode is enhanced by series and parallel resonance at the electrode. The resonance frequency was shifted by the presence of the electro-optic crystal, which was placed on the electrode for use in the sampling technique. We also showed that the measured electric field distribution at the edges of the electrode was different from the results numerically obtained by an equivalent circuit model.
