“…It is also easier to fabricate high-quality groove or slot waveguides because one can obtain ultra-smooth grooves or slots by etching a single crystal silicon substrate and evaporating high-quality films. 78,79,[81][82][83] In such whole groove or slot integration, the hybrid wire/spacer/film laser is still usable, as it does not require many laser sources. Some advantages and disadvantages of different SPP waveguides are listed in Table 1.…”

The properties of propagating surface plasmon polaritons (SPPs) along one-dimensional metal structures have been investigated for more than 10 years and are now well understood. Because of the high confinement of electromagnetic energy, propagating SPPs have been considered to represent one of the best potential ways to construct next-generation circuits that use light to overcome the speed limit of electronics. Many basic plasmonic components have already been developed. In this review, researches on plasmonic waveguides are reviewed from the perspective of plasmonic circuits. Several circuit components are constructed to demonstrate the basic function of an optical digital circuit. In the end of this review, a prototype for an SPP-based nanochip is proposed, and the problems associated with building such plasmonic circuits are discussed. A plasmonic chip that can be practically applied is expected to become available in the near future. Keywords: nanophotonics; plasmonic chip; plasmonic circuit; surface plasmons; waveguide INTRODUCTIONThe technologies of semiconductor integrated circuits and modern electronic integrated devices are rapidly approaching their fundamental limits in terms of both speed and data transmission rate (DTR).1 One of the promising solutions to these problems is using light rather than electrons in the functional processing components.2 However, the feasibility of fabricating nanoscale photonic devices may be limited because the diffraction limit of light is dominant when the size of a photonic device is close to or smaller than the wavelength of light in the material. Surface plasmon polaritons (SPPs), electromagnetic waves coupled to charge oscillation at the metal dielectric interface, can circumvent the diffraction limit and achieve localisation of electromagnetic energy in nanoscale regions that are considerably smaller than the wavelengths of light in the material. 3 The electromagnetic field perpendicular to the interface between metal and dielectric decays exponentially with distance from the metal surface while maintaining the long-range propagation of electromagnetic energy along the surface. This essential feature of SPPs can enable the fabrication of photonic components and optical signal processing devices at the sub-wavelength scale.Surface plasmons (SPs) include the localised type (localised surface plasmons, LSPs) and propagating type (propagating surface plasmon polaritons, PSPPs). For the purpose of optical signal transportation and nanophotonic circuits, only PSPPs will be considered in this review, and they are referred to as SPPs hereafter. Because of the unique properties of tightly confined SPPs on metal structures, various types of metallic nanostructures, such as nanoparticle chains, 4-7 thin metal films, 8 metal slits, 9 grooves, 10 chemically synthesised metal nanowires (NWs)

“…In the same time, it was reported that atomically flat Au layers can be obtained on special substrates like mica [53] and LiF [54] using sputtering techniques. The obtained gold layers were very smooth, the RMS in the latter case was 0.2 nm (but the thickness was 80 nm).…”

Ultra-thin films with low surface roughness that support surface plasmon-polaritons in the infra-red and visible ranges are needed in order to improve the performance of devices based on the manipulation of plasmon propagation. Increasing amount of efforts is made in order not only to improve the quality of the deposited layers but also to diminish their thickness and to find new materials that could be used in this field. In this review, we consider various thin films used in the field of plasmonics and metamaterials in the visible and IR range. We focus our presentation on technological issues of their deposition and reported characterization of film plasmonic performance.

“…Recently, to capture, control and manipulate the light at the preferred wavelengths, particle- [4][5][6][7][8][9][10] and aperture-based nanoantennas with different geometries have been studied [11][12][13][14][15][16][17]. It has been observed the changes in the shape and dimensions provide adjustable resonance frequencies [18][19][20][21] and aperture based systems have great advantages for sensing applications [12][13][14][15]. A number of different vibrational modes, symmetric stretching, a bending, and an asymmetrical stretching mode, can be the case for a chemical or biological molecule.…”
