The properties of zone center optical phonons in ternary cubic InxGa1-xN were studied. The infrared reflectance spectroscopy and auxiliary Raman spectra confirmed the one-mode behavior of phonons. The optical phonons behavior was found to be type I and was arised from both the small mass ratio of Ga to In atoms and the strong ionicity of Ga-N and IN-N bonds.
