Silicon nitride waveguide integrated with cross bowtie nanoplasmonic antenna for tunable dipole plasmon resonance and maximum local field enhancement

Abstract. A single transverse electric mode silicon nitride strip waveguide functionalized with cross bowtie nanoplasmonic antenna is investigated, and then its tunable dipole plasmon resonance and maximum local field enhancement are numerically analyzed. The cross bowtie antenna is composed of a horizontal bowtie parallel to the propagation and a vertical bowtie parallel to the electric field. We demonstrate that the dipole plasmon resonance wavelength of localized surface plasmon resonance of cross bowtie antenna can be tuned by the horizontal bowtie, specifically by the edge length of its regular triangular nanoprisms, and the dipole plasmon resonance wavelength is independent of the horizontal gap. We also show that the maximum local field enhancement of cross bowtie antenna can be tuned by the vertical bowtie, specifically by the edge length of its regular triangular nanoprisms. The tunable dipole plasmon resonance and maximum local field enhancement of integrated cross bowtie nanoplasmonic antenna can practically be applied for on-chip sensing applications.
