Research paper thumbnail of Surface plasmon polaritons on nanostructured surfaces and thin films

Such metallic nanostructures act as polaritonic crystals for surface polaritons, in analogy to photonic crystals for light waves. In this paper surface polariton Bloch mode spectrum on the structured surfaces and films is overviewed and manifestations of various surface plasmon modes in the optical properties of metallic nanostrnctures are considered. Surface plasmon polaritons me emerging as a new optical information carrier that enables signal manipulation and processing on the subwavelength scale and development of integrated photonic circuits. 1. INTaODUCTION Optical functionality of metallic nanostructures is determined by the interaction of photons with collective excitations of conduction electrons at a metal surface. Surface plasmon polariton (SPP) is an electromagnetic excitation on the surface of good metals that consists of a surface plasmon, itself a collective excitation of electrons close to a metal surface, and a photon. SPPs play a crucial role in optical propelties of randomly rough and artificially structured metal surfaces and films, such as reflection, transmission, scattering, second-harmonic generation, surface enhanced Raman scattering, etc. [I]-[4]. Two-dimensional optics of surface polaritons on metal interfaces has been developed that provides tools to manipulate and direct SPP waves on a surface in analogy to light beams in three-dimensional optics [3]. Very recently, short-wavelength SPPs which exist at optical frequencies have been used to demonstrate nanoscale imaging of surface structures in the far-field, breaking the resolution limits of conventional microscopy [5]. An important class of metallic systems for optical applications is based on periodically nanostructured metal films. Such metallic nanostmctures have been considered for applications as nanoscale surface-plasmnn-based sensors, for the enhancement of nonlinear optical processes and can lead to the development of all-optical photonic circuits where they can be used as passive as well as active photonic components [3]. Behaviour of surface plasmon polaritons on a periodically structured surface is governed by the same rules as of electron behaviour in a crystalline lattice or photons in a periodic structure such as a photonic crystal. In analogy, a nanostructured metal surface or thin film can be considered as surface-polaritonic crystal. The optical properties of such SPP crystals are determined by surface polariton behaviour in a lattice formed by a nanostructure on a surface. Among the optical phenomena related to SPPs on periodic surface structures are resonant absorption, reflection as well as enhanced transmission of light through metallic films [6]-[10], polarization conversion during couplingtdecoupling of photons to surface polariton modes [I I], nonlinear optical effects at low light intensities [12]. All these phenomena are in one or another way related to the SPP Bloch modes formed on a periodically structured surface. Very recently, analytical descriptions of surface polariton states on periodic surfaces and films were developed [9],[13],[14]. This resulted in understanding of the role of the SPP states related to different branches of the Brillouin zones in photon tunnelling through a metal film. The exact knowledge of the electromagnetic mode structure was used to describe near- and far-field properties of the transmitted light. In this paper surface polariton modes on periodically nanostructured metal surfaces and thin films are overviewed in relation to various optical properties of metallic nanostructures. Surface plasmon polaritons are emerging as a new optical information carrier that enables signal manipulation and processing on the subwavelength scale. This suggests the possibility of building a new class of photonic devices and development of all-optical integrated photonic circuits. Numerous applications can be envisaged in classical and quantum optical information processing and optical communications.

An optical fiber tip frustrates the evanescent part of the light existing in the near-field of the sample. We combine classical and fluorescence near-field probing, in the photon tunneling configuration and demonstrate a novel effect which, to our knowledge, has not been reported yet. An improvement of the discrimination of the microspheres is observed in near-field when fluorescence light is emitted owing to the presence of an evanescent part of the fluorescence light in the vicinity of the sample. This part which is normally compelled to remain confined to the near-field of the sample is converted into propagating light by the probe and this tunneling fluorescence light brings additional information about the sample. This effect is highly sensitive to the incident (i.e., excitation) wavelength and it is found that when the observed confinement is maximum, a slight change in the incident wavelength entails noticeable changes in the near-field images.
