Talk 1
Title: New Principle and New Structure Semiconductor Terahertz Devices for Beyond 5G
Speaker: Prof. Akira Satou (Tohoku University Research Institute of Electrical Communication)
Abstract: TBD
Talk 2
Title: Resonant-tunneling-diode terahertz signal generator for sensing applications
Speaker: Prof. Safumi Suzuki (Institute of Science Tokyo)
Abstract:
The terahertz frequency band lies between microwaves and infrared light, and sensing technologies that exploit its unique properties have attracted considerable attention as applications close to practical deployment. Resonant tunneling diode (RTD)-based terahertz signal sources are mass-producible semiconductor devices that offer compact size, room-temperature operation, low power consumption, and low cost, making them well suited for such applications. This presentation introduces the fundamental operating principles of RTD devices, recent advances in improving their core performance, including high-frequency oscillation and high-output-power operation, the development of new functionalities such as frequency-comb generation, and the latest progress in application development based on these devices.
