Hybrid optical modes, consisting of a unique linear combination of LO, TO and IP (interface polariton) modes satisfying both elastic and electromagnetic boundary conditions, are described in a continuum approximation. Mode patterns and mode dispersion are obtained which agree with microscopic calculations. Inter- and intrasubband electron scattering rates are obtained which also agree with those derived on the basis of microscopic models.
