Abstract
In this paper we present the modeling, design and fabrication of high-speed photonic modulators for use at high GHz, namely millimeter wave (MMW), frequencies based on the electro-optic materials, such as LiNbO3. To accurately design the traveling wave MMW modulators rigorous EM numerical tools are used to determine the propagation characteristics of both the optical and MMW waveguides. Extensive studies have been made to achieve an optimal design, which includes a close refractive index match between optical and MMW wave and a reduction of MMW propagation loss. The designed devices have been fabricated and tested with a modulation up to 135GHz.
