Photonic density of states of two-dimensional quasicrystalline photonic structures
A large photonic band gap (PBG) is highly favorable for photonic crystal devices. One of the most important goals of PBG materials research is identifying structural design strategies for maximizing the gap size. We provide a comprehensive analysis of the PBG properties of two-dimensional (2D) quasicrystals (QCs), where rotational symmetry, dielectric fill factor, and structural morphology were...
متن کاملTwo-dimensional photonic crystal accelerator structures
July 2003 Two-dimensional photonic crystal accelerator structures∗ Benjamin M. Cowan† Stanford Linear Accelerator Center, Stanford University, Stanford, California 94309 Abstract Photonic crystals provide a method of confining a synchronous speed-of-light mode in an all-dielectric structure, likely a necessary feature in any optical accelerator. We explore computationally a class of photonic cr...
متن کاملSemiconductor Three-Dimensional Photonic Crystals with Novel Layer-by-Layer Structures
Three-dimensional photonic crystals (3D PhCs) are a fascinating platform for manipulating photons and controlling their interactions with matter. One widely investigated structure is the layer-by-layer woodpile structure, which possesses a complete photonic bandgap. On the other hand, other types of 3D PhC structures also offer various possibilities for controlling light by utilizing the three ...
متن کاملPhotonic band gaps with layer-by-layer double-etched structures
Periodic layer-by-layer dielectric structures with full three-dimensional photonic band gaps have been designed and fabricated. In contrast to previous layer-by-layer structures the rods in each successive layer are at an angle of 70.5° to each other, achieved by etching both sides of a silicon wafer. Photonic band-structure calculations are utilized to optimize the photonic band gap by varying...
متن کاملA Layer-Stripping Solution of the Inverse Problem for a One-Dimensional Elastic Medium
A fast algorithm for recovering profiles of density and Lame parameters as functions of depth for the inverse seismic problem in an elastic medium is obtained. The medium is probed with planar impulsive P and SV waves at oblique incidence, and the medium velocity components are measured at the surface. The interconversion of P and SV waves defines reflection coefficients from which the medium p...
