Pi. Khadzhi et al., Characteristic features of the steady-state transmission (reflection) by athin semiconductor film in the exciton part of the spectrum, QUANTUM EL, 29(6), 1999, pp. 542-545
The steady-state transmission (reflection) of laser radiation by a thin sem
iconductor film was investigated taking into account the exciton-photon and
elastic exciton-exciton interactions. Under certain conditions the resulta
nt dependences of the transmission by a thin film on the amplitude of the i
ncident radiation and on the detuning from a resonance exhibit a hysteresis
, which can be explained by a shift of the exciton level when the exciton d
ensity is increased.
