“…For example, a one-dimensional thin film MSL is known to possess properties that cannot be reduced to those of the separate layers. Also, phenomena such as giant magnetoresistance (GMR) 1 , large out-of-plane magnetic anisotropy 2 , and magnetic field controlled photonic 3 and magnonic [4][5][6] band gaps have been observed. However, in other situations MSLs can be thought of as "effective media" with "effective" parameters 7 that represent an average of those of the constituent layers.…”

We report a simple theoretical derivation of the spectrum and damping of spin waves in a cylindrical periodically structured magnetic nanowire ͑cylindrical magnonic crystal͒ in the "effective-medium" approximation. The dependence of the "effective" magnetic parameters upon the individual layer parameters is shown to be different from the arithmetic average over the volume of the superlattice. The formulas that are obtained can be applied firstly in the description of spin-wave dispersion in the first allowed band of the structure and secondly in the design of a magnonic crystal with band gaps in an arbitrary part of the spin-wave spectrum.

“…15 For this reason, the defect modes have been used for filters only under the limit of the normal incidence being at a particular wavelength; otherwise, transmission peaks appear at the other wavelengths under oblique incidence. [16][17][18] Recently, compared with traditional all-dielectric Fabry-Pérot interference filters, 19,20 various designs have been proposed for novel features, such as graphene, 21 superconductor, [22][23][24] semiconductor, 25 and liquid crystal 26 -dielectric PCs. To overcome the angular effect influences, some innovative reports have been published, in which negative refractive-index materials, 27 hyperbolic metamaterials, 28,29 and so on were selected as special performance materials to achieve insensitivity to incident angle and polarization.…”

Angular-adjustable single-channel narrow-band filter based on one-dimensional photonic crystal heterostructure

In this work, we designed a narrow-band filter based on a one-dimensional photonic crystal heterostructure featuring an angle-adjustable single-channel. The design presented here is based on a quarter-wave reflector with a mirror defect layer in the middle of the structure. By combining two defective one-dimensional photonic crystals (PCs), we obtained a heterostructure in which the two sub-PCs had the wavelengths of their defect modes, that is, the same at one incident angle and different at all other incident angles. This structure possessed the single-channel resonant peak in the transmission spectrum under either a normal or an oblique incident angle, and the angle-adjustability was related to the two modifying parameters. The filter based on this heterostructure possessed not only a narrow passband but also a sharp angular pass breadth. These properties have potential applications in angular tunable, single-channel narrow-band filters.

“…The one-dimensional nanostructures of photonic crystals with bismuth-substituted iron garnet (Bi: IG) layers are perspective for magnetooptical (MO) sensors in optoelectronic devices allowed significant rotation of the polarization plane of the transmitted light. One of the first proposed structures in magnetophotonics was the microcavity based on nonmagnetic dielectric Bragg mirrors (BM) and a Bi: IG layer [1][2][3][4][5]. In such structures, Faraday and Kerr rotation enhancement is achieved most effectively.…”

New original Tamm plasmon-polaritons (TPP) structures with Bi-substituted iron garnet and Au plasmonic layers were proposed, synthesized and investigated. The structures with single and double garnet layers were modelled to form a TPP mode at the center of photonic band gab. The top Au layer has the gradient thickness varied in the range from 0 to 65.2 nm. It was found the features of TPP resonances as a function of the thickness of metal coating. The resonances on TPP have the maximum optical quality factor and transmission at the vicinity of Au thickness of 30 nm. These configurations are optimum to form the highest intensity of electric field of light wave in the area of the magnetic layers. It was found the spectral blue and red shifts of TPP mode with increasing of Au thickness. The blue and red shifts can be explained respectively by structural and thickness changes of Au coating. The maximum resonant values of Faraday rotation were –2.1° at 664 nm and –12.3° at 645 nm for structures with single and double garnet layers, respectively, and thickness of Au coating of 65.2 nm.
