摘要
Zn-diffused Mach-Zehnder intensity modulators operating at 1.55-mum wavelength are demonstrated on a z-cut and a y-cut LiNbO3 substrate for the first nine. The switching voltages are measured and the corresponding values of switching voltage-length product are 9.6 V-cm and 13.5 V-cm for the z-cut and y-cut modulators, respectively. Both the modulated extinction ratios are about 20 dB. The results show that the Zn-diffused modulators not only have electro-optic tunability as great as that of the Ti-diffused ones, but also have more flexibility for device fabrication.
