Abstract

This is a general presentation of light interaction with acoustic waves in GaAs-Ga1-xAlxAs superlattices. Two kinds of vibrations are considered : the Rayleigh surface waves propagating parallel to the free surface, and the bulk acoustic waves with wavevectors perpendicular to the layers of the superlattice. The folding of the longitudinal acoustic branch allows the probing of bulk acoustic waves up to 1000 GHz. Two theoretical approaches are used for the study of the vibrational modes in superlattices : the theory of elasticity and a linear diatomic chain model, only the former being developed here. This lecture contains a description of the high contrast and high resolution Brillouin scattering set up used for the investigation of acoustic waves in these semiconductor structures. A brief insight on light scattering by modes of the optical branches is also given.
