W-band optical modulators using organic EO polymer waveguides and patch antenna arrays
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.
