N2 - Magnetophotoluminescence and change in photoluminescence (PL) intensities, due to far-infrared irradiation at the cyclotron resonance (CR) magnetic fields, in modulation-doped (Formula presented) single heterostructures are measured. The changes in PL intensities due to CR absorption strongly depend on the Landau-level filling factor (Formula presented) and CR energy; i.e., the Landau-level separation. When (Formula presented) and CR energy is more than intersubband energy separation, luminescence from the ground subband is almost quenched and that from the second subband is greatly enhanced by CR absorption.
