采用屏蔽相位速度匹配行波电极，研制了一种特性阻抗接近50 Ω的宽带低驱动电压Ti：LiNbO 3马赫-曾德尔光调制器。在1.52 μm波长下，获得了20 GHz（3dB光）的宽调制带宽和4.7V的低驱动电压。
A wideband and low-driving voltage Ti:LiNbO3 Mach-Zehnder optical modulator of nearly 50 Ω characteristic impedance has been developed employing a shielded-phasevelocity-matching travelling-wave (TW) electrode. Both wide modulation bandwidth of 20 GHz (3 dB optical) and low driving voltage of 4.7 V were attained at 1.52 μm wavelength.
