Abstract
Microscopic models of longwavelength zone-centre optical modes in supe rlattices predict an anisotropic behaviour of the dipole active modes. Recent micro-Raman data has unambiguously demonstrated this anisotrop y for LO1 and it is shown here that a continuum model that simply mixe s confined LO and interface modes gives very good agreement with the d ata.
