      Large ultrafast optical nonlinearities in As-rich GaAs 

      Benjamin, S. D.; Othonos, Andreas S.; Smith, P. W. E. (1994)
      The measurement of large Ultrafast bandgap-resonant optical nonlinearities in As-rich samples of GaAs that have been grown at low temperatures is reported. Light-induced refractive index changes of magnitude greater than ...

      Ultrafast dynamics of nonlinear absorption in low-temperature-grown GaAs 

      Benjamin, S. D.; Loka, H. S.; Othonos, Andreas S.; Smith, P. W. E. (1996)
      We present the results of a study of the subpicosecond dynamic behavior of optically induced absorption changes in low-temperature-grown GaAs. We show that the observed behavior is dominated by mid-gap trap states, and can ...
