High-power even- and odd mode emission from linear arrays of resonant-tunneling-diode (RTD) oscillators in the 0.4- to 0.8-THz frequency range
Fanqi Meng, Zhenling Tang, Petr Ourednik +4
Resonant tunneling diode (RTD) oscillators possess the highest oscillation frequency among all electronic THz emitters. However, the emitted power from RTDs remains limited. Here,…

Terahertz detection with graphene FETs: photothermoelectric and resistive self-mixing contributions to the detector response
Florian Ludwig, Andrey Generalov, Jakob Holstein +4
Field-effect transistors coupled to integrated antennas (TeraFETs) are photodetectors being actively developed for the THz frequency range ( 100 GHz - 10 THz). Among them, Gr…
