A linear-chain model with variable force constants for the couplings at heterojunctiorts is used to calculate the spectrum of confined longitudinal-optical (LO) phonon frequencies in a short-period strained-layer superlattice. Even for the case of a superlattice with only two atomic monolayers in ea
