Research Activities
Terahertz (sub-millimeter) coherent electromagnetic waves are expected to explore the potential application fields of future information and communications technologies. We are developing novel, ultra-broadband integrated signal-processing devices/systems operating in the millimeter and terahertz frequency regime.
Ultra-Broadband Devices and Systems (Prof. Otsuji)
Research topics
- Creation of Graphene Terahertz Lasers.
- Creation of 2D-Atomically-Thin-Layered Hetero-junctions and their Applications to Novel Terahertz Photonic Devices.
- Physics of Graphene Dirac Plasmons and its Terahertz Functional Applications.
- Creation of EIC (Energy-Information-Communication) Converged Resilient Network Infrastructure towards Super-Smart Society
We are developing novel, integrated electron devices and circuit systems operating in the millimeter-wave and terahertz regions. III-V- and graphene-based active plasmonic heterostructures for creating new types of terahertz lasers and ultrafast transistors are major concerns. By making full use of these world-leading device/circuit technologies, we are exploring future ultra-broadband wireless communication systems as well as spectroscopic/imaging systems for safety and security.
