Abstract:
We present a rigorous Bloch mode scattering matrix method for modeling two-dimensional photonic crystal
structures and discuss the formal properties of the formulation. Reciprocity and energy conservation considerations
lead to modal orthogonality relations and normalization, both of which are required for mode calculations
in inhomogeneousmedia. Relations are derived for studying the propagation of Bloch modes through
photonic crystal structures, and for the reflection and transmission of these modes at interfaces with other
photonic crystal structures.
