  • Title: Extreme nonlinear optical enhancement in chalcogenide glass fibers with deep-subwavelength metallic nanowires.
    Author: Ung B, Skorobogatiy M.
    Journal: Opt Lett; 2011 Jul 01; 36(13):2527-9. PubMed ID: 21725468.
    Abstract:
    A nanostructured chalcogenide-metal optical fiber is proposed. This hybrid nanofiber is embedded with a periodic array of triangular-shaped deep-subwavelength metallic nanowires set up in a bowtie configuration. Our simulations show that the proposed nanostructured fiber supports a guided plasmonic mode enabling both subwavelength field confinement and extreme nonlinear light-matter interactions, much larger than a bare chalcogenide nanowire of comparable diameter. This is all achieved with less than 3% by volume of metal content.
