We report a Raman study of the phonon mode of (AlxGa1-x)0.51In0.49P quaternary alloys lattice matched to GaAs over the whole range of compositions. From the composition dependence of spectra it has been confirmed that the three-mode behavior of the alloy corresponding to the three binary compositions: AlP-, GaP-, and InP-like phonon modes may occur.
