    • Giant tunable Faraday effect in a semiconductor magneto-plasma for broadband terahertz polarization optics 

      Arikawa, Takashi; Wang, Xiangfeng; Belyanin, Alexey A.; Kono, Junichiro (2012)
      We report on a giant Faraday effect in an electron plasma in n- InSb probed via polarization-resolved terahertz (THz) time-domain spectroscopy. Polarization rotation angles and ellipticities reach as large as π/2 and 1, ...
    • Superradiant Decay of Cyclotron Resonance of Two-Dimensional Electron Gases 

      Zhang, Qi; Arikawa, Takashi; Kato, Eiji; Reno, John L.; Pan, Wei; Watson, John D.; Manfra, Michael J.; Zudov, Michael A.; Tokman, Mikhail; Erukhimova, Maria; Belyanin, Alexey; Kono, Junichiro (2014)
      We report on the observation of collective radiative decay, or superradiance, of cyclotron resonance (CR) in high-mobility two-dimensional electron gases in GaAs quantum wells using time-domain terahertz magnetospectroscopy. ...
