LINEAR CIRCULAR-DICHROISM IN NONLINEAR ABSORPTION OF LIGHT IN A QUANTUM-WELL

The far infrared absorption spectrum caused by optical transitions of holes between size-quantization subbands is calculated for p-GaAs/AlGa As(001) quantum-well structures. The selection rules for optical trans itions at the center of the two-dimensional Brillouin zone are determi ned. Allowance is made for resonant saturation of one-photon electroni c transitions between size-quantized subbands of light and heavy holes . The linear circular dichroism in one-photon nonlinear (resonant) and two-photon absorption of light in a size-quantized well are investiga ted. (C) 1998 American Institute of Physics.
