Abstract :
The characteristics of high-speed LiNbO3 electrooptic interferometric modulators/switches are discussed from the viewpoint of optimization of device performance. Specific calculations of the impedance, effective microwave index, and microwave attenuation parameter are presented as a function of the microwave electrode parameters including the buffer layer thickness. The authors have found that the optimization procedure is considerably simplified when the range of electrode and microwave parameters that satisfy a given bandwidth requirement is first determined
