Superfluorescence from Magnetically Formed Quantum Dots: the Excitation Pulse-Width Dependence Academic Article uri icon

abstract

  • We investigated the laser pulse-width dependence of dense plasmas confined within the magnetic length of In0.2Ga0.8As/GaAs multiple quantum wells under high magnetic fields up to 31 T. To fully fill the Landau levels of effectively zero-dimensional system, we used intense femtosecond (fs) laser pulses to create carrier densities near 1013/cm2. The observed photoluminescence showed a characteristic of superfluorescence, above critical magnetic field when being excited by pulses shorter than coherence buildup time.
