Abstract (in Japanese) (See Japanese page) 
(in English) We demonstrate 64 Gbps operation in a compact Si photonic crystal optical modulator that employs meander line electrodes and compensate for the phase mismatch between slow light and RF signals. Although slow light increases the modulation efficiency, the phase mismatch limits the operation speed. The meander line electrodes improved the cutoff frequency up to 38 GHz and greatly improved the quality of the modulation characteristics at 25–32 Gbps. Clear open eye was observed even at 64 Gbps.
