| Tunable plasma wave resonant detection of optical beating in high electron mobility transistor (2006) | |||||||||||||||
Abstract | |||||||||||||||
| We report on tunable terahertz resonant detection of two 1.55 µm cw-lasers beating by plasma waves in AlGaAs/InGaAs/InP high-electron-mobility transistor. We show that the fundamental plasma resonant frequency and its odd harmonics can be tuned with the applied gate-voltage in the range 75–490 GHz. The observed frequency dependence on gate-bias is found to be in good agreement with the theoretical plasma waves dispersion law. | |||||||||||||||
