Abstract

The propagation performances of a double-chain splitter waveguide consists of coupled silver nanowires are investigated for different structures. We show that the efficiency of energy transport along the waveguide and split at a Y-junction due to surface plasmonic coupling is significantly depends on the parameters chosen for the structure such as radius of nanowire, opening angle of splitter and illuminating wavelength. The optimal structure for efficiently guiding and splitting the light at 600 nm is discussed in detail.
