Paper Abstract

The intersubband light emission of GaAs/GaAlAs quantum cascade lasers is measured under pulsed magnetic fields parallel to the current, up to 60 T. A giant modulation of the laser intensity is observed with complete suppression of the laser emission when the energy spacing between intersubband Landau quantized states matches the GaAs optical phonon energy. When the level separation is not equal to the phonon energy, the laser output increases as a result of quenched phonon emission from the upper subband electrons. In this situation, the laser threshold current was found reduced by a factor of two.
