Abstract

The seamless transition between microscale photonics and nanoscale plasmonics requires overpassing different waveguiding mechanisms and a few orders of magnitude in the lateral dimension. Exploiting gap plasmon-polariton waves both at the microscale and nanoscale with an ultrashort (few micrometers) non-adiabatic tapered gap plasmon waveguide, we show theoretically that very high-power transfer efficiency (similar to 70%) is achieved. The same mechanism may be used to harvest impinging light waves and direct them into a nanhole or slit to exhibit an anomalous transmission without the conventional periodic structures. The interplay of plasmonic and oscillating modes is analyzed. (c) 2006 Optical Society of America.
