Paper Abstract

Two competing methods of optical waveguide formation in LiNb03 are the indiffusion of Ti and the exchange of Li with protons in an acidic solution. Numerous reports, both pro and con, have been made concerning waveguides fabricated using these two methods. In this paper, we would like to compare guided-wave Mach-Zehnder interferometric modulators fabricated using both of these methods. We will discuss the fabrication and testing of these devices including measurements of Vff, the voltage required to drive the modulator from its maximum output to its minimum output, the electrode capacitance, optical damageability, and waveguide bend and branch losses.
