We have studied the reflectance properties of ZnSe epilayers deposited on GaAs substrates by metal-organic vapor-phase epitaxy. For layer thicknesses in the range of a micrometer, reflectance oscillations are observed, and are due to Fabry-P\'erot modes in the upper branch of the polariton. This observation is made possible due to the large exciton Rydberg energy in ZnSe and due to the subsequent long-energy extension of this branch of the polariton before its coupling with the 2s-related exciton branch.
