Abstract
We report on Raman scattering in nanostructures with InP quantum dots in an In0.48Ga0.52P matrix embedded in an In0.48Al0.52P waveguide. At resonant e xcitation with the quantum dot excitons, broad Raman peaks corresponding to acoustic and optical vibrations were observed. Their polarization was stud ied for in-plane propagation of the exciting and scattered light in forward scattering geometry. In comparison with the conventional backscattering co nfiguration, the Raman signals are drastically enhanced due to the increase d scattering volume. [S0163-1829(98)01643-9].
