Abstract
Frequency dependent drive voltage is reported in velocity matched, packaged , Mach-Zehnder interferometers, made on Z-cut, Y-propagating LiNbO3, with a nd without etched ridges. Drive voltages of similar to 7 V at 40 GHz are de monstrated, with the etched ridge device showing a 1/2-1 V advantage. Micro wave modeling allowed the extraction of the effects of dispersion in materi al properties, occurring near the acoustic resonance, on bandwidth and driv e voltage.
