Numerical Analysis And Design Of Dielectric To Plasmonic Waveguides Couplers
In this work, efficient directional coupler composed of dielectric waveguides and metallic film has been analyzed in details by simulations using finite element method (FEM). The structure consists of a step-index fiber with dielectric core, silica cladding, and a metal nanowire parallel to the core. The results show that an efficient conversion of optical dielectric modes to long range plasmonic is possible. Low insertion losses in conjunction with short coupling length and a broadbanddoi:10.5281/zenodo.1128866 fatcat:bcvxcsrq65h4riarzf2e4angym
