Abstract

We introduce a biosensor scheme comprising a plasmonic microring resonator coupled with a plasmonic bus waveguide. The detection principle is based on the violation of the surface plasmon polariton resonance condition for the microring (which is sensitive to refractive index changes). Analytical calculations and simulations in COMSOL Multiphysics are presented. As a result, we obtained main characteristics of the sensor, such as sensitivity (S= 1200 nm) and Q-factor (Q≈ 100).
