Abstract
Mechanism of the optical detection of cyclotron resonance via emission from 2D electron gas in modulation doped quantum wells and in high el ectron mobility structures of GaAs/AlGaAs is discussed based on the re sults of time-resolved optical detection of cyclotron resonance. An im portant role of impact ionization processes is demonstrated. We also s how that microwave radiation destroys emission enhancement at the Ferm i level and the relevant mechanism is proposed.
