Abstract
The subject matter of this report is the analysis of the dependence of the diffraction efficiency of volume phase gratings on the state of polarization of the read-out wave. I revise the derivation of the two-wave coupled-wave theory starting from Maxwell's equations. The new formulation of the theory differs from the well-known results of Kogelnik's theory mainly in three aspects: (1) The new theory incorporates the effect of form birefringence caused by the layered structure of the refractive index profile. (2) The dephasing parameter which describes the dephasing between the read-out wave and the signal wave has a definite parity. Consequently, the new theory is invariant under the reciprocity transformation of optics. (3) The grating strength for the p-polarization depends not only on the read-out geometry but on the profile of the refractive index as well.
