Paper Abstract

The coupling between waveguides via cavities fabricated in 2D photonic crystals is investigated within a numerical framework. We demonstrate that the symmetry of the modes plays an important role in light propagation through waveguides coupled by cavities. Two different situations are addressed: the structures are defined varying the geometrical parameters and varying the dielectric constant ε. In both situations we show that if the symmetry of the waveguide mode does not correspond to that of the localized mode of the cavity the coupling is negligible.
