ABSTRACT
A design of high optical throughput nanoscale light sources has been proposed based on plasmonic wedge waveguides. It provides localization of the 1500 nm wavelength light at the output of less than 30×30 nm2 area at about 80% coupling efficiency from a dielectric loaded surface plasmon polariton waveguide and nearly 90% efficient power deposition in the absorbing media placed at the output for an experimentally viable 10 nm apex radius of the wedge. Such nanoscale light sources can be useful for high-density data storage, scanning near-field optical microscopy, and sensing.

    We excite a guided plasmonic mode in slot waveguides of subwavelength width. With a phase- and polarization-sensitive near-field microscope, we measure the electric field of the mode for a range of slot widths from 40 to 120 nm. The field is experimentally found to be antisymmetric across the...

    The interference patterns of the surface plasmon polaritons (SPPs) on the metal surface from a 'point' source are observed.

    We show that the emission of light from a dye layer through an adjacent thin silver film is maximal for a silver thickness of approximately 50 nm. This effect is explained as the result of competition between enhancement of the electric field at the metal surface due to the excitation of a...
