Paper Abstract
Terahertz detectors based on GaAs/AlGaAs heterostructure were investigated at low temperatures and high
magnetic fields. A response of detectors showed a line caused by a cyclotron resonance transition which was
accompanied by several peaks originated form excitation of magnetopasmons. Illumination with a visible light
caused an increase of the plasma concentration and resulted in a change of the magnetoplasmon spectrum. An
analysis of spectra allowed to determine changes in the plasmon dispersion relation with a visible light which
gives a tool to tune a THz response of a plasmonic detector.
