Phonon and polariton modes in a superlattice

Abstract

Calculations of the dispersion of phonons and polaritons in a superlattice show that the frequencies of the phonon and polariton modes may be prescribed by proper design. These modes may be useful as Raman source and Reststrahlen filters. © 1972 The American Institute of Physics.
