  An analytical formulation for the band structure and Bloch modes in
elliptically birefringent magnetophotonic crystals is presented. The model
incorporates both the effects of gyrotropy and linear birefringence generally
present in magneto-optic thin film devices. Full analytical expressions are
obtained for the dispersion relation and Bloch modes in a layered stack
photonic crystal and their properties are analyzed. It is shown that other
models recently discussed in the literature are contained as special limiting
cases of the formulation presented herein.
