Title of Paper:

Light Propagation in Curved Silver Nanowire Plasmonic Waveguides

Journal:

Nano Letters

Summary:

Plasmonic waveguides made of metal nanowires (NWs) possess significant potential for applications in integrated photonic and electronic devices. Energy loss induced by bending of a NW during light propagation is critical in affecting
its performance as a plasmonic waveguide. We report the characterization of the pure bending loss in curved crystalline
silver NW plasmonic waveguides by decoupling the energy loss caused by bending and propagation. The energy attenuation coefficiency due purely to bending was also determined, which exhibited an exponential relationship with the bending radius. Finite-difference-time-domain (FDTD) methods were utilized for theoretical simulations, which matched the experimental results well.
