AB  - Surface plasmon polaritons (SPP) are electromagnetic waves bound by the collective oscillations of free carrier plasma to the surface of a conductor surrounded by dielectric. These waves can be localized, concentrated or manipulated simply by processing the conductor surface. The choice of a convenient conductor is quite limited by the availability of natural materials and strong absorption losses associated with free electron plasma. For this reason new alternative plasmonic materials are actively being researched and developed. Most common approaches to this problem include doping of nonmetallic materials and fabrication of metal-dielectric nanocomposite metamaterials. In this contribution we perform an analysis of the suitability of the use of the heterometallic multilayers consisting of copper and nickel. Copper is an excellent plasmonic material, but the problem is formation of natural copper oxides on the surface. Therefore for this purpose a layer of nickel is used as a protection against oxidation of copper. Laminate composite structures of alternating nanocrystalline nickel and copper films on a cold-rolled polycrystalline copper foils were fabricated by electrochemical deposition technique. We simulated the electromagnetic properties of subwavelength Cu/Ni multilayers by the 2D finite element method using realistic material parameters to assess different electromagnetic modes. Our results show that the pair Cu/Ni can be viewed as an alternative tailorable plasmonic material. It has also been shown that it is possible to fabricate plasmonic structures without applying any complex lithographic processes.

AB  - In this work we review methods to decrease the optical absorption losses in metamaterials. The practical interest for metamaterials is huge, but the possible applications are severely limited by their high inherent optical absorption in the metal parts. We consider the possibilities to fabricate metamaterial with a decreased metal volume fraction, the application of alternative lower-loss plasmonic materials instead of the customary utilized noble metals, the use of all-dielectric, high refractive index contrast subwavelength nanocomposites. Finally, we dedicate our attention to various methods to optimize the frequency dispersion in metamaterials by changing their geometry and composition in order to reach lower absorption, which includes the use of the hypercrystals. The final goal is to widen the range of different metamaterialbased devices and structures, including those belonging to transformation optics. Maybe the most important among them is the fabrication of a novel generation of all-optical or hybrid optical/electronic integrated circuits that would operate at optical frequencies and at the same time would offer a packaging density and complexity of the contemporary integrated circuits, owing to the strong localization of electromagnetic fields enabled by plasmonics.

AB  - Plasmonic nanocomposites are a new class of
materials that offers unprecedented opportunities to tailor the
optical response, including the possibility to design their spectral
and spatial dispersion at will. This includes the optical
parameters rarely or never met in nature, which opens a path
toward plasmonic metamaterials and the wide new area of
transformation optics. Responsible for such a unique behavior
are bound surface modes propagating along interfaces between
materials with different signs of relative dielectric permittivity
known as surface plasmon polaritons (SPP). Most metals possess
negative relative permittivity in optical range due to the existence
of free electron plasma. However, they also exhibit large
absorption losses and are bound to a given spectral range defined
by the metal itself, which is the reason why alternative plasmonic
materials are being actively sought upon. One possible way to
extend the toolbox of available materials is to use alternating
metal-dielectric or metal-metal layers – the one-dimensional
plasmonic crystals. Typically gold and silver are used for the
metal part due to their large conductance and generally
favorable properties. In this contribution we perform an analysis
of the suitability of the use of copper for plasmonic
nanocomposites. Its oxidation, the main barricade towards its
more widespread use in plasmonics, is avoided by combining it
with nickel. We utilize ab initio analysis by 2D finite element
modeling and realistic material parameters to assess different
electromagnetic modes. Tailorability of the response is attained
by simple changing of the Cu to Ni fill factor. The analyzed CuNi plasmonic crystals are convenient for simple, low cost
biochemical sensors and superabsorbers.

AB  - Plasmonics and optical metamaterials offer possibilities for numerous applications in different fields, from transformation optics and chemical sensing to merging the beneficial properties of electronic and optical circuits. Crucial for their function are interfaces between materials of which one has to exhibit negative value of relative dielectric permittivity due to the existence of free electron plasma. However, the choice of convenient materials is rather limited and their performance is severely impaired by strong absorption losses. This is the reason why alternative plasmonic media are currently of an increasing interest. In this contribution we consider one such medium, the heterometallic multilayer consisting of copper and
nickel. Copper is an excellent plasmonic material, but needs protection against surface oxidation, a role fulfilled by nickel layers which simultaneously form interfaces supporting surface waves. We describe our proposed heterometallics and consider their electromagnetic properties and experimental fabrication. Ab initio numerical simulations were done using the finite element method for Cu-Ni multilayers on a copper substrate. Laminate composite structures of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces can be obtained by depositing layers at a very narrow
spacing. Our results show that Cu-Ni pairs are a viable
alternative to conventional plasmonic media, while the
electrodeposition approach offers acceptable structural and electromagnetic parameters with large area and good uniformity at a low cost.

AB  - The main problems with plasmonics for devices are connected with its very nature implying the need to use free electron conductors, mostly good metals like silver or gold. The choice of natural materials and thus their operating ranges, as defined by their plasma frequency, is rather limited. Also, absorption losses in good conductors are quite high. Because of that alternative plasmonic materials are of increasing interest. In this contribution we consider the possibility to design plasmonic crystals incorporating a pair of plasmonic materials (all-metal plasmonic crystals). For the sake of technological simplicity, we limit ourselves to one-dimensional structures with a pair of alternating layers with subwavelength periodicity. Such structures behave as strongly anisotropic effective media tailorable by design. In other words, instead of considering waveguiding in usual IMI (insulator-metal-insulator) and MIM (metal-insulator-metal) we investigate MMM (metal-metal-metal) and generally PPP (plasmonic-plasmonic-plasmonic) structures. For the plasmonic material pair we choose copper and nickel. The properties of Cu as a plasmonic material are excellent, however it oxidizes when exposed to atmosphere. Besides serving as the second plasmonic material, Ni also protects Cu layers against corrosion. Electromagnetic simulations to obtain optical properties of our all metal plasmonic crystal were performed using the finite element method.

AB  - We analyze the fundamental properties of optical waves referred to as Tamm plasmon modes (TPMs) which are tied to the interface of a semi-infinite two-phase metallodielectric superlattice with an arbitrary homogeneous capping medium. Such modes offer new ways of achieving high electromagnetic field localization and spontaneous emission enhancement in the vicinity of the interface in conjunction with absorption loss management, which is crucial for future applications. The homointerface, formed when the capping medium has the same permittivity as one of the superlattice constituents, is found to support a TPM whose dispersion overlaps the single-interface surface plasmon polariton (SPP) dispersion but which has a cut off at the topological transition point. In contrast, a heterointerface formed for an arbitrary capping medium, is found to support multiple TPMs whose origin can be traced by considering the interaction between a single-interface SPP and the homointerface TPM burried under the top layer of the superlattice. By carrying out a systematic comparison between TPMs and single-interface SPPs, we find that the deviations are most pronounced in the vicinity of the transition frequency for superlattices in which dielectric layers are thicker than metallic ones.
