Photonic crystals, amorphous materials, and quasicrystals
Photonic crystals consist of artificial periodic structures of dielectrics, which have attracted much attention because of their wide range of potential applications in the field of optics. We may also fabricate artificial amorphous or quasicrystalline structures of dielectrics, i.e. photonic amorphous materials or photonic quasicrystals. So far, both theoretical and experimental studies have b...
متن کاملRhombellanic Crystals and Quasicrystals
Design of some crystal and quasicrystal networks, based on rhombellane tiling,is presented. [1,1,1]Propellane,is a synthesized organic molecule; its hydrogenated form, the bicyclo[1.1.1]pentane,may be represented by the complete bipartite graph K2,3 which is the smallest rhombellane. Topology of translational and radial structures involving rhombellanes is described in terms of vertex symbol, c...
متن کاملActive Materials in Photonic Crystals
I analyze new phenomena arising from embedding active materials inside of photonic crystal structures. These structures strongly modify the photonic local density of states (LDOS), leading to quantitative and qualitative changes in the behavior of active materials. First, I show that the emission spectrum of pointlike sources inside an “omniguide” is strongly modified by features resembling one...
متن کاملPhotonic crystals and negative refractive index materials
We review the research of our group on propagation of electromagnetic waves in photonic crystals (PCs) and micrometer scale left-handed materials (LHMs). The main topics that we focus on regarding PCs are the modification of the spontaneous emission rate of sources embedded into them, their ability to produce beams with high directionality and their negative refraction and focusing properties, ...
متن کاملPhotonic Materials and Devices
Our recent advances in solid-state optoelectronic materials and devices will be reviewed. In the area of glass optics, fabrication of novel microstructured and multi-core fibers and their use in realizing single mode lasers will be summarized. In organic and plastic optics, photorefractive polymers for 3D display applications and nonlinear optical polymers for high speed modulators in RF photon...
