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. %G English %2 https://hal.science/hal-00105454/document %2 https://hal.science/hal-00105454/file/APL_photodetection2.pdf %L hal-00105454 %U https://hal.science/hal-00105454 %~ CNRS %~ UNIV-VALENCIENNES %~ UNIV-MONTP2 %~ IEMN %~ IES %~ GES %~ UNIV-MONTPELLIER %~ CEM2 %~ UNIV-LILLE %~ UM1-UM2 %~ TEST-UPHF
