Role of Short-Range Order and Hyperuniformity in the Formation of Band Gaps in Disordered Photonic Materials.
We study photonic band gap formation in two-dimensional high-refractive-index disordered materials where the dielectric structure is derived from packing disks in real and reciprocal space. Numerical calculations of the photonic density of states demonstrate the presence of a band gap for all polarizations in both cases. We find that the band gap width is controlled by the increase in positiona...
متن کاملDesigner disordered materials with large, complete photonic band gaps.
We present designs of 2D, isotropic, disordered, photonic materials of arbitrary size with complete band gaps blocking all directions and polarizations. The designs with the largest band gaps are obtained by a constrained optimization method that starts from a hyperuniform disordered point pattern, an array of points whose number variance within a spherical sampling window grows more slowly tha...
متن کاملPhotonic Band Gaps and Unusual Photon Transport in Hyperuniform Disordered Structures
We demonstrate that hyperuniform disordered structures support electromagnetic states with very different transport properties, ranging from Bloch-like modes to diffusive states with characteristic time scales almost two-orders of magnitude larger. ©2012 Optical Society of America OCIS codes: 130.5296, 130.7408, 160.5293, 160.5298 Recently, a new class of disordered materials with large complet...
متن کاملPhase Properties of One-Dimensional Quaternary Photonic Crystals
In this paper, properties of reflection phase in one-dimensional quaternary photonic crystals combining dispersive meta-materials and positive index materials are investigated by transfer matrix method. Two omnidirectional band gaps are located in the band structure of considered structure. However, we limit our studies to the frequency range of the second wide band gap. We observe that the val...
متن کاملInfluence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals
In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...
