We present a method for describing optical properties of inhomogeneous media at mesoscopic scales. When the volume of interaction varies, the effective polarizability tensor introduces a new length scale characterizing the structural morphology.
Limitations on the physical realization of objects with point singularities in the refractive index are explored through transformation optics. Details of a lossless air/semiconductor composite structure for implementation of three structures are worked out.
A new type of tellurite chalcogenide glass is proposed and simulated at the microscopic molecular level using GAMESS. The ab initio study shows that the optical linear polarizability alpha and second-order hyperpolarizability gamma per unit increase ~1.5 times and ~2 times respectively by replacing O with S in chain-like structures Te<Ox>Te (X=O or S), resulting in an estimation of linear refractive...
We report on a metamaterial sample that demonstrates double-negative index behavior at the shortest wavelength to date. We also discuss the controlled resonance tuning of optical magnetism in materials by using of liquid crystals.
Nonlinear index was investigated in undoped and Yb-doped monoclinic double-tungstates for EparNm and EparNp polarized 819 nm light. Anisotropic n2 with maximum for EparNm in all investigated compounds is proportional to the rare earth ion polarizability.
Quantum rods (QRs) are incorporated into polymers that are doped with azo dyes via an energy transfer process. The polarization-dependent refractive-index change allows four-dimensional optical data storage as well as other polarization-controlled photonic applications.
