We report on Raman scattering in nanostructures with InP quantum dots in an (Formula presented) matrix embedded in an (Formula presented) waveguide. At resonant excitation with the quantum dot excitons, broad Raman peaks corresponding to acoustic and optical vibrations were observed. Their polarization was studied for in-plane propagation of the exciting and scattered light in forward scattering geometry. In comparison with the conventional backscattering configuration, the Raman signals are drastically enhanced due to the increased scattering volume.
