Abstract

We have used optically excited ultrashort electrical pulses to measure the magnetoplasmon resonance of a two-dimensional electron gas formed in an AlGaAs/GaAs heterostructure at frequencies up to 200 GHz. This is accomplished by incorporating the sample into a guided wave probe operating in a pumped (formula presented) system. We are able to detect the resonance by launching a stimulus pulse in the guide, and monitoring the system response in a time-resolved pump-probe arrangement. Data obtained from measurements yield resonant frequencies that agree with the magnetoplasmon dispersion relation.
