Abstract
Optical phenomena connected with intersubband electron transitions in speci ally designed structures with tunnel-coupled GaAs/AlGaAs quantum wells have been investigated. The observed birefringence and absorption modulation un der longitudinal electric held applied parallel to the quantum layers have been explained by electron heating and electron transfer in real space.
