The bulk exciton polaritons in ternary mixed crystals are investigated in the Born-Huang approximation. The numerical results of the polariton frequencies as functions of the wave-vector and the compositions for ternary mixed crystals AlxGa1-xAs, CdxZn1-xSe, and AlxGa1-xN are obtained and discussed. The new dispersion characteristics for exciton-polaritons in TMC systems are found in comparison with binary crystals. The splitting of the two branches of exciton- polariton frequencies varys nonlinearly with the composition of ternary mixed crystals and has a minimum in the long-wavelength range.
Keywords:polariton, exciton, ternary mixed crystal
