Abstract

We measured frequency responses of half-wave voltage V_π and chirp parameter α₀ of LiNbO₃ modulators below 1 GHz range using optical heterodyne scheme with an acousto-optic modulator. The coefficients of variation of the measured values of V_π and α₀ are 0.2 % and 2 %, respectively. We observed strong dependency of V_π and α₀ on the frequency.
