We present recent results on terahertz emission/detection utilizing two-dimensional plasmons in different types of InGaAs/InP, GaAs/AlGaAs and GaN/AlGaN nanometric high electron mobility transistors. The emission frequencies correspond to the estimated characteristic plasma wave frequencies and the emission exhibits threshold behavior against the drain bias, indicating instability driven coherent self oscillation. For detection, gate lengths below 100 nm in InGaAs/InP systems allow for a resonant voltage tunable detection at frequencies up to 3 THz. By using those devices we demonstrate experimental evidence of the plasma wave imaging at room temperature. Presented devices will become efficient future detectors/sources for terahertz imaging especially if they are integrated in detector/source arrays. |
