研究概要

The terahertz (THz) frequency range (100 GHz to 10 THz), positioned between radio waves and light waves on the electromagnetic spectrum, holds promise for a wide range of applications including wireless communications, imaging, sensing, and medical technology. Especially, research and development are actively underway to utilize THz waves for wireless carrier frequencies as ultimately high-frequency radio waves for next-generation wireless communication systems (Beyond 5G; B5G). These systems, characterized by ultra-high speed, ultra-high capacity, ultra-low latency, and ultra-low power consumption, serve as the foundational technology for realizing “Society 5.0”—a sustainable, ultra-smart future society where virtual and real spaces are highly integrated.

Realizing the next-generation B5G wireless communication systems requires device and system technologies capable of freely utilizing “ultra-broadband” electromagnetic waves spanning from optical to terahertz frequencies, and from microwaves to baseband. This research laboratory specifically aims to create sub-THz/THz-band semiconductor devices and optical-wireless-convergence devices based on novel physics, principles, and materials.

We are currently working on the following research themes.

Research Theme #1: THz Plasmonic Detectors
