Cover Story: Plasmonic biosensing has had a huge impact on both research and industry, particularly thanks to the biosensors based on surface plasmon resonance (SPR), which are currently produced by different commercial companies. Here, we propose a plasmonic biosensor based on a vertically coupled plasmonic racetrack resonator and a thin-film plasmonic waveguide. The main advantages over SPR biosensors include a small footprint size and possibility of on-chip integration. In addition, it can be fabricated using planar microelectronic technology. The operation of the proposed device is based on resonance shift in the racetrack resonator due to changes of the refractive index of the media above it. In the manuscript, we analyzed the sensitivity and detection limit of this biosensor depending on its essential characteristics.View this paper.
