Abstract
In-plane optical anisotropy was measured in polarization-resolved reflectivity experiments on a CdTe-based multiple quantum well sample. Parabolic confining potentials were achieved by introduction of controlled Mg mole fraction. Addition of 6 molar % of Mn across the sample structure allowed us to control the light – heavy hole splitting by giant Zeeman effect. We observed an enhancement of the measured anisotropy when the light- and heavy hole bands were brought together by the magnetic field. A model calculation produced a phenomenological description of the observed behavior. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
