ABSTRACT We fabricate and characterize one-dimensional magnetic (rather than dielectric) photonic crystals for the first time. Our model system is a one-dimensional periodic lattice of gold-wire pairs. Each pair can be viewed as a magnetic coil with two slits and represents a "magnetic atom." Strong coupling between the resulting magnetic-dipole resonance and the Bragg resonance is accomplished by an adjacent dielectric slab waveguide, giving rise to an avoided crossing at near-infrared wavelengths. Our experimental findings are in excellent agreement with theory.

    ABSTRACT: We numerically study near-field-induced coupling effects in metal nanowire-based composite nanostructures. Our multi-layer system is composed of individual gold nanowires supporting localized particle plasmons at optical wavelengths, and a spatially separated homogeneous silver slab supporting delocalized surface plasmons. We show that the localized plasmon modes of the composite structure, forming so-called magnetic atoms, can be controlled over a large spectral range by changing the thickness of the nearby metal slab. The optical response of single-wire and array-based metallic structures are compared. Spectral shifts due to wire-mirror interaction as well as the coupling between localized and delocalized surface plasmon modes in a magnetic photonic crystal are demonstrated. The presented effects are important for the optimization of metal-based nanodevices and may lead to the realization of metamaterials with novel plasmonic functionalities.

    ABSTRACT: Unidirectional spectral responses generated by a plasmonic cavity formed by two asymmetric metasurfaces are reported and interpreted using interference theory and a transmission line (TL) model. Illuminated by a p-polarized plane wave from the front or back side, the plasmonic cavity functions as either an absorber or reflector according to the illumination side at a certain wavelength under Fabry–Perot cavity resonance. Based on interference theory, it is revealed that the phase shift of reflection at each metasurface plays a key role in the formation of the unidirectional spectral response, while the TL model demonstrates that the unidirection comes from the difference of characteristic impedance between the two metasurfaces. This work provides profound understanding of the underlying physics for unidirectional spectral response generated by a plasmonic cavity and benefits diverse applications such as direction-involved active plasmonic devices and unidirectional thermal emissions.

    ABSTRACT: A new kind of one-dimensional (1D) photonic crystal (PC) filter is reported in this paper. This kind of a filter is a dimerlike heterostructure constructed by two 1D dielectric and magnetic PCs. Compared with traditional filters based upon 1D pure dielectric PCs, the new one has the advantage of extending the omnidirectional filtering (ODF) band and simplifying the structure due to its large wave impedance contrast between the composites and the reasonable arrangement of the layer thicknesses and the number of periods. To design such a filter, we adopted a combined method by the transmission matrix method and the decimal genetic algorithm, and finally we obtained a high-precision 1D PC filter design which not only shows a very broad relative ODF band of 1.496, but also has a simple structure with less total number of layers and less total thickness. The simplification of structure is conductive to device fabrication. Besides, an example with low dispersive and low dissipative magnetic material for microwave application is also discussed.
