Abstract
Birefringence and absorption modulation under electron heating in a longitu dinal electric field in the tunnel-coupled GaAs/AlGaAs quantum wells have b een found and investigated in the spectral region corresponding to intersub band electron transitions. The observed phenomena are explained by electron heating in electric field and electron transfer in real space. The equilib rium absorption spectra at different lattice temperatures are analyzed.
