It is shown that the problem of anharmonic coupling of polariton, Stokes, and anti‐Stokes waves in simple piezoelectric cubic crystals leads to a system of three linear equations (basic equations) if the parametric approximation is used for the pump wave. The solutions of these basic equations are six coupled plane waves, each consisting of a polariton, Stokes, and Anti‐Stokes wave component. The dispersion functions of the six coupled waves are the roots of the corresponding secular equation. Also the coupling factors of the wave components can be derived form the basic equations. The coupled waves very sensitively depend on three dielectric functions. These dielectric functions can be transformed into the alternative form of Kurosawa relations which are useful for the interpretation and for applications.
