“…Several different structures have been used as waveguides to transport surface plasmons of highly localized modes. Metal strips [19 -21] , wedges [22] , grooves and slots in metal fi lms [23 -27] , and dielectric strips on metal fi lms [28,29] have been investigated as plamonic waveguides. Crystalline metal nanowires, which are usually prepared by chemical methods, are another kind of waveguides.…”

The fast development of plasmonics have greatly advanced our understanding to the abundant phenomena related to surface plamon polaritons (SPPs) and improved our ability to manipulate light at the nanometer scale. With tightly confi ned local fi eld, SPPs can be transmitted in waveguides of subwavelength dimensions. Nanophotonic circuits built with plasmonic elements can be scaled down to dimensions compatible with semiconductor-based nanoelectronic circuits, which provides a potential solution for the next-generation information technology. Different structures have been explored as plasmonic waveguides for potential integration applications. This review is focused on metallic nanowire waveguides and functional components in nanowire networks. We reviewed recent progress in research about plasmon generation, emission direction and polarization, group velocity, loss and propagation length, and the near-fi eld distribution revealed by quantum dot fl uorescence imaging. Electrical generation and detection of SPPs moves towards the building of plasmonic circuits, where bulky external light sources and detectors may be omitted. The coupling between metal nanowires and emitters is important for tailoring light-matter interactions, and for various potential applications. In multi-nanowire structures, plasmon signal control and processing are introduced. The working principles of these nanowire-based devices, which are based on the control to the near fi eld distributions, will become the design rule for nanophotonic circuits with higher complexity for optical signal processing. The recent developments in hybrid photonic-plasmonic waveguides and devices are promising for making devices with unprecedented performance.

“…This geometry is of fundamental importance in nano-photonics, although the relatively large portion of energy propagating in the surrounding regions may restrict the compactness of the waveguide. On the other hand, plasmonic waveguides can provide subwavelength confinement by storing optical energy in electron oscillations within dissipative metallic regions [2][3][4][5][6][7][8][9][10][11][12][13]18 .…”

“…On the one hand, SPP characteristics are strongly dependent on the optical properties of both metal and dielectric media, which makes them useful for the development of biological sensors. [4][5][6] On the other hand, SPP modes are evanescent waves strongly bounded to the metaldielectric interface with the potential to overcome the light diffraction limit and therefore they become suitable candidates for light guiding at the subwavelength scale [7][8][9] or for super resolution far-field optical microscopy. 10,11 One step further in the progress of plasmonics is associated with the development of active plasmonic devices, that is, the realization of materials combinations or configurations that allow the control of SPP properties by an external agent.…”

Surface plasmon polariton ͑SPP͒ excitation effects on the magneto-optical ͑MO͒ activity of Au capped Ag/Co/Ag trilayers are studied as a function of Co thickness. An enhancement of the transverse MO Kerr signal under SPP excitation as compared with that obtained without SPP excitation is measured with a maximum value of 150 times obtained for the trilayer with 8 nm Co. Such enhancement on the magneto-optical activity due to SPP excitation is also five times higher than that obtained in Au/Co/Au trilayers in similar conditions. The lower optical absorption in the studied range and the sharper plasmon resonance of Ag vs Au are responsible for these values. On the other hand, magnetic field-induced SPP wavevector modulation ͑⌬k / k͒ SPP is studied for these trilayers and compared both with previous results in the Au/Co/Au system as well as with the theory. In the wavelength considered here, the obtained values are similar for both Ag-and Au-based structures and on the order of 10 −4 , pinpointing the role of the magnetic layer on the SPP wavevector modulation.
