The numerical dispersion calculations in long-period GaAs/AlAs super-lattice were performed using a local theory with retardation as well as an ef­fective medium approximation. The splitting of the dispersion branches near the transverse optical phonon frequencies and phonon-like to photon-like modes transition were found to depend on the superlattice spatial period. The characteristic frequencies of bulk modes and crossing point of disper­sion branches estimated analytically with the use of an effective medium approximation were found to agree with the results of rigorous solution.
