报道了一种具有周期性极性反转结构的ＬｉＴａＯ３电光相位调制器，在１６．２５ＧＨｚ调制频率下，实现了微波与光波的准速度匹配。在合成超短光脉冲实验中获得了１６．２５ＧＨｚ下５７ｒａｄ的调制度，调制带宽达１．８５ＴＨｚ（ＦＷＨＭ）
A LiTaO3 electro-optical phase modulator with periodic polarity reversal structure is reported. The quasi-speed matching between microwave and light is achieved at a modulation frequency of 16.25GHz. In the synthesis of ultrashort optical pulse experiment obtained 57rad modulation at 16.25GHz, the modulation bandwidth of 1.85THz (FWHM)
