abstract

A hybrid coupler composed of a slot plasmonic waveguide and a dielectric waveguide is proposed and its coupling characteristics are analyzed. The simulation results show that the ultra-small mode of the slot plasmonic waveguide can be excited efficiently by the dielectric waveguide mode within the coupling length of just several microns, which provides an interface between the slot plasmonic devices and dielectric devices. Meanwhile, based on this hybrid the coupler, a highly integrated refractive index sensor could be realized.
