Modal and wavelength conversions in plasmonic nanowires

We show that plasmonic nanowire-nanoparticle systems can perform nonlinear wavelength and modal conversions potentially serve as building blocks for signal multiplexing novel trafficking modalities. When a surface plasmon excited by pulsed laser beam propagates in nanowire, it generates localized broadband continuum at the nanowire well active locations defined sites where nanoparticles are absorbed (enhancement sites). The local response may couple to new sets of propagating modes enabling complex routing optical signals through spectral conversions. Different aspects influencing presented, including parameters defining formation subsequent nanowire.
