Photonic band structure computations.
We introduce a novel algorithm for band structure computations based on multigrid methods. In addition, we demonstrate how the results of these band structure calculations may be used to compute group velocities and effective photon masses. The results are of direct relevance to studies of pulse propagation in such materials.
متن کاملBand structure computations of metallic photonic crystals with the multiple multipole method
A method for the computation of the band structure of two-dimensional photonic crystals is presented. It is well suited for crystals including materials with arbitrary frequency-dependent dielectric constants. The technique can be applied to study photonic crystals with irregularly shaped ~noncircular! elements. This method is based on the multiple multipole method. In order to find the solutio...
متن کاملAn Approximate Analytic Model for Evaluating the Photonic Band Structure of a 2-D Octagonal Photonic Quasicrystals
In this work, using perturbation technique we have developed an approximate analytic model for evaluating the band structure of a 2-D octagonal photonic quasicrystal (PQC). Although numerical techniques are being used for evaluating such band structures, developing a numerical model to the best of our knowledge this work is the first instance of reporting helps to understand the physical proper...
متن کاملPhotonic Band Structure and Transmittance of the Superconductor Photonic Crystal
The photonic crystal (PhC) is formed with a dielectric periodic structure and exhibits new electromagnetic phenomena (John, 1987). It shows some properties analog to the semiconductor, such as the photonic band structure (PBS) including photonic passing bands and photonic band gaps (PBGs), and complicated dispersion relations. In analogous to the electron transport in the semiconductor, the Blo...
متن کاملPhotonic band structure of ZnO photonic crystal slab laser
We recently reported on the realization of ultraviolet photonic crystal laser based on zinc oxide Appl. Phys. Lett. 85, 3657 2004 . Here we present the details of structural design and its optimization. We develop a computational supercell technique that allows a straightforward calculation of the photonic band structure of ZnO photonic crystal slab on sapphire substrate. We find that despite t...
