“…1,2 As a result of such a study, phenomena like total suppression of reflection, 3 transformation of polarization, [4][5][6] enhanced light transmission, 7,8 formation of band gaps [9][10][11][12] and other interesting properties of plasmonic crystals have been discovered. Lately, a great deal of attention has been devoted to the creation of optical elements for SPP's, [13][14][15][16][17] as well as to the efficient coupling of light into and out of SPP's.…”

Scattering of surface plasmon polaritons by one-dimensional inhomogeneities

The scattering of surface plasmons polaritons by a one-dimensional defect of the surface is theoretically studied by means of both Rayleigh and modal expansions. The defects considered are either relief perturbations or variations in the permittivity of the metal. The dependence of transmission, reflection, and out-of-plane scattering on parameters defining the defect is presented. We find that the radiated energy is forwardly directed ͑with respect to the surface plasmon propagation͒ in the case of an impedance defect. However, for relief defects, the radiated energy may be directed into the backward or forward ͑or both͒ direction, depending on the defect width.

“…16͒ and a means to control their propagation. 17 SPPs are also involved in the observation of enhanced transmission through otherwise opaque me-tallic films perforated with a periodic array of subwavelengths holes. 18,19 A key aspect of these developments is that not only does the introduction of wavelength-scale structure introduce a richness into the resulting surface plasmon modes, it also allows incident light to be coupled into and out of these modes.…”

Transition from localized surface plasmon resonance to extended surface plasmon-polariton as metallic nanoparticles merge to form a periodic hole array

We present results of experiments to determine the dispersion of the plasmon modes associated with periodic silver nanoparticle and nanohole arrays fabricated using an extension of the nanosphere lithography technique. Ordered monolayers of polystyrene nanospheres were used as a deposition mask through which silver was deposited by thermal evaporation, subsequent removal of the nanospheres thus leaving an array of metallic nanoparticles. By reactive-ion etching of the nanospheres in an oxygen plasma prior to silver deposition, arrays consisting of particles of increasing size were fabricated. The extremities of the particles eventually merge to create a continuous metallic network perforated by subwavelength holes, thus allowing a study of the particlehole transition. Combining optical measurements of transmittance and reflectance with information gained using scanning electron microscopy, three separate regimes were observed. For low etch times the samples comprise mainly individual nanoparticles and the optical response is dominated by localized surface plasmon resonances that show no dispersion. As the etch time is increased almost all of the nanoparticles merge with adjacent particles, although many defects are present-notably where some particles fail to merge, a small gap being left between them. The presence of these defects prevents an abrupt structural transition from metallic nanoparticles to a continuous metallic film perforated by an array of nanoholes. The presence of such gaps also results in dispersion data that lack clearly defined features. A further increase in etch time leads to samples with no gaps: instead, a continuous metal film perforated by a nanohole array is produced. The optical response of these structures is dominated by extended surface plasmon-polariton modes.

“…In this context plasmonics overcomes the standard limitation imposed by diffraction in photonic waveguides since SPPs are indeed naturally confined in a 2D environment. Grooves (Seidel, 2004), stripes (Lamprecht et al, 2001;Barnes et al, 2003;Berini, 2000) chains of particles (Quidant et al, 2004;Nomura et al, 2005) and metal photonic-band-gap geometries (Barnes and Sambles, 2006;Bozhevolnyi et al, 2001) have been studied in this context for their ability to guide or block SPP waves. However other problems like the SPP damping during the propagation must be studied precisely before applications to technology might be realized.…”

We present an overview of recent progress in "plasmonics". We focus our study on the observation and excitation of surface plasmon polaritons (SPPs) with optical near-field microscopy. We discuss in particular recent applications of photon scanning tunnelling microscope (PSTM) for imaging of SPP propagating in metal and dielectric wave guides. We show how near-field scanning optical microscopy (NSOM) can be used to optically and actively address remotely nano-objects such as quantum dots. Additionally we compare results obtained with near-field microscopy to those obtained with other optical far-field methods of analysis such as leakage radiation microscopy (LRM).
