Résumé: Terahertz (THz) electronics is attracting increasing attentions due to the recent “beyond-5G” research. On the other hand, it may surprise many that devices for THz wave generation and detection had in fact been reported as early as one century ago, and even the CMOS-based low-cost THz circuit also already has more than 15 years of history. Despite those advances, exploration of unique and practical applications of the THz technology, especially the applications for THz chip-scale systems, is still far from enough. In this talk, we introduce some recent research outcomes in this regard. Showcased prototypes include high-angular-resolution radars, ultra-miniaturized and unclonable RFIDs, molecular spectrometer-based gas sensors and clocks, low-heat-load cryogenic interconnects, among others.
