Abstract

Plasmonic antennas have recently been combined to nanophotonic silicon nitride (SiN) waveguides for demonstrating all-on-chip Surface Enhanced Raman Spectroscopy (SERS). This achievement relied on bowtie antennas engineered to maximize the generated Raman signal. Here, we present numerical investigation of an arch dipole (AD) antenna identically patterned on a rib waveguide and compare it to the best engineered bowtie antenna. Our study shows a 23 fold improvement over the state of the art thus promising shorter integration time and high Signal-to-Noise Ratio which should ultimately enable the detection of on-chip SERS signals originating from a single antenna.
