Abstract

In Beyond 5G wireless communication, the radio-over-fiber (RoF) technology that transmits signal waveforms of terahertz waves (0.1-10 THz) using optical fibers will be important. To realize such technology, it is required to develop a device that converts a terahertz signal into an optical signal. Organic electro-optic (EO) polymers can have large EO coefficients (> ~100 pm/V) and realize ultra-high-speed optical modulation of several hundred GHz or more. In this research, we prototyped 150-GHz-band antenna-coupled optical modulators with EO polymer waveguides and patch antenna arrays using a transfer and bonding method of a poled EO polymer film.
