The simplified model of the optical phonon dispersion has been analyzed in the case of binary semiconducting compound. As it is well known, the typical solution describing vibrations of one-dimensional atomic chain composed of two types of ions exhibits the maximal value of the optical phonon frequency corresponding to the wavenumber q = 0. This behavior of optical phonon modes is an excellent model of lattice vibrations for many important semiconductors, such as GaAs or ZnTe.
