Paper Abstract

We present a review of recent achievements in nanoscale optical devices based on energy transport with surface plasmon-polaritons and localized surface plasmons. Chains of metal subwavelength-size particles and stripes are used to build straight waveguides, s-bends, y-junctions and beam shaping devices. Strong enhancement of near-field in nanogaps between particles leads to efficient light emission from such nanoantennas. Development of surface plasmon nanoptics stimulates further progress in near-field imaging. To improve resolution of scanning near-field optical microscope (SNOM) it is necessary to improve light throughput in tapered metal-coated SNOM probes. This is achievable due to resonant surface plasmons that propagate in corrugated probes.
