We charaterize the mmWave-optic modulation performances of thin-film lithium niobate modulators at frequencies up to 325 GHz with a measured 3-dB electro-optic bandwidth of 170 GHz and a 6-dB bandwidth of 295 GHz. The device also shows a low RF half-wave voltage of 8.3 V measured at an ultrahigh modulation frequency of 250 GHz.
