Abstract
In Beyond 5G wireless communication, it is expected that the radio over fiber (RoF) technology that transmits signal waveforms of terahertz waves (0.1-10 THz) using optical fibers will be important. In this research, we fabricated optical modulators consisting of the patch antenna arrays and electro-optic (EO) polymer waveguides, aiming to develop a device that directly modulates light by irradiating electromagnetic waves in the W band (75-110 GHz). We also prototyped a device structure with a ground electrode to improve the efficiency of the electromagnetic wave detection.
