Abstract
The wave interference behaviors between two interacting defects in a two-dimensional photonic-band-gap system are studied by using the multiple-scattering method. By injecting electromagnetic wave energy at one defect, we find oscillatory resonant energy transfer between two defects when both defect mode frequencies lie inside a full gap. When one of the defect mode frequency merges with the pass band forming a resonant state, energy leakage as well as frequency modulation are observed due to the interaction among the defect mode, the resonant states, and the band states. These classical resonant behaviors are realizable in simple two-dimensional photonic-band-gap systems.
