Intraband absorption of light in quasi-two-dimensional systems in external electric and magnetic fields

Intraband light absorption in parabolic quantum wells is studied, when the electric field is directed along the size quantization axis and the magnetic field is parallel to the plane of the quantum well layer. When the light polarization vector is parallel to the spatial quantization axis then the direct optical transitions between the size-quantized levels are possible. In this polarization the maximal value of the light absorption coefficient is reached the great values (3 x 102 cm-1) and the absorption frequency depends on the magnetic field strength
