摘要：

Microscopic models of longwavelength zone-centre optical modes in superlattices predict an anisotropic behaviour of the dipole active modes. Recent micro-Raman data has unambiguously demonstrated this anisotropy for LO1 and it is shown here that a continuum model that simply mixes confined LO and interface modes gives very good agreement with the data.
