TLDR
High quality metallic wires (diameters down to 260nm) are fabricated using direct fiber drawing from a gold-filled cane, showing coupling of light from the glass-core to plasmonic resonances on the wire, causing dips in the transmission at specific wavelengths.Abstract:
We report the successful production of high-quality gold wires, with diameters down to 260nm, by direct fiber drawing from a gold-filled fused-silica cane. The stack-and-draw technique makes it straightforward to incorporate a conventional step-index core, adjacent to the gold wire, in the cane. In the drawn fiber, strong coupling of light from the glass core to SPP resonances on the gold wire is observed at specific well-defined wavelengths. Such embedded wires have many potential applications, for example, as nanoscale electrodes, in nonlinear optical plasmonics, and as near-field scanning optical microscope tips.read more

A multi-core holey fiber based plasmonic sensor with large detection range and high linearity
TL;DR: It is found that not only phase matching but also loss matching plays a key role in the coupling process between the fundamental mode and plasmonic mode, which transforms from incomplete coupling to complete coupling with increasing analyte RI.
