Fabrication and properties of gallium metallic photonic crystals
Gallium metallic photonic crystals with 100% filling factor have been fabricated via infiltration of liquid gallium into opals of 300-nm silica spheres using a novel high pressure–high temperature technique. The electrical resistance of the Ga-opal crystals was measured at temperatures from 10 to 280K. The data obtained show that Ga-opal crystals are metallic network with slightly smaller tempe...
متن کاملFilling Fraction Dependent Properties of Inverse Opal Metallic Photonic Crystals
Metallic photonic crystals, metal-based structures with periodicities on the scale of the wavelength of light, have attracted considerable attention due to the potential for new properties, including the possibility of a complete photonic bandgap with reduced structural constraints compared to purely dielectric photonic crystals, unique optical absorption, thermally stimulated emission behavior...
متن کاملMetallic Photonic Crystals : Fabrication , Physical Properties , and Applications
Metallic photonic crystals (MPCs) have a number of unique properties due to the presence of a high conductivity and a plasma frequency in the metal constituent. It is desirable to investigate the physical properties of MPCs in the visible spectrum in order to reduce losses in the metal, therefore requiring periodicity on the nanoscale. Our team is concentrating on two physical embodiments of MP...
متن کاملPhotonic crystals of coated metallic spheres
It is shown that simple face-centered-cubic (fcc) structures of both metallic and coated metallic spheres are ideal candidates to achieve a tunable complete photonic bandgap (CPBG) for optical wavelengths using currently available experimental techniques. For coated microspheres with the coating width to plasma wavelength ratio lc/λp ≤ 10% and the coating and host refractive indices nc and nh, ...
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...
