Superfluorescence from dense electron–hole plasmas under high magnetic fields Conference Paper uri icon

abstract

  • Ultrafast optical excitation of a dense electron-hole plasma in In x Ga 1-x As multiple quantum wells in high magnetic fields (>20T) produces cooperative radiative recombination between conduction and valence band Landau levels (LL). Above a critical threshold, the emission is characterized by very narrow LL line widths, superlinear increase with increasing field and laser excitation fluence, and stochastic directionality from shot to shot. Here, we investigate the effects of temperature and excitation geometry on the emission properties.
