Radio over fiber (RoF) technology, which transmits terahertz wave (0.1-10 THz) signal waveforms using optical fiber, is attracting attention for the realization of ultra-high-speed wireless communication in Beyond 5 G. In this study, we prototyped and evaluated W-band (75-110 GHz) antenna-coupled optical modulators using electro-optic polymer waveguides and non-coplanar patch antennas with the aim of realizing devices that directly convert a radio signal to an optical signal in RoF.
