Abstract
General relations concerned with the irreducible representations of th e radiation field in arbitrary three-dimensional photonic lattices are derived. Based on this relation, an efficient method for the mode ass ignment that excludes unphysical quasilongitudinal eigenmodes is prese nted. This method is applied to a simple cubic lattice with O-h symmet ry as an example; and its uncoupled modes that cannot be excited by an incident plane wave are identified.
