| Popis: | The existence of an absolute photonic bandgap in the near-infrared for two-dimensional periodic dielectric structures is discussed for photons propagating in the plane of such 2D crystals. A special emphasis is put on the influence of the shape and size of the filling pattern on the absolute bandgap formation. A very large absolute photonic bandgap is predicted for 2D crystals formed by etching into a semiconductor slab a periodic array of large vertical cylindric voids of circular cross-section arranged in a triangular lattice. The technological feasibility of such “optimum” air/GaAs 2D crystals by standard processing techniques (electron beam lithography and reactive ion etching) is demonstrated. |
