Abstract :
The design and fabrication parameters needed to obtain a low-loss coplanar waveguide structure were determined. A large optical bandwidth (more than 23 GHz) and low driving voltage (5 V) Ti:LiNbO/sub 3/ Mach-Zehnder interferometer type optical modulator at a wavelength of 1.52 mu m, using a conventional and thick coplanar waveguide type electrode structure.<>
