Plasmonic sensors provide great sensitivity to minute quantities ofanalytes and provide excellent detection. This sensitivity is crucial for applicationsin biomedical diagnostics, environmental monitoring, and food safety. In thisinvestigation, a plasmonic refractive index sensor based on key ring shaped resonatorconsisting of a microring resonator and two rectangular resonator is proposed. FiniteDifference Time Domain method is used to study the transmittance characteristicsof the sensor. The device exhibits quadruple Fano resonance with highest sensitivityof 2521.7 nm/RIU. Other performance parameters such as FOM (Figure of Merit),Q factor and Detection limit are also been calculated, with values 98.8 RIU−1, 99.6and 0.01 respectively. Additionally, the effects of different geometrical configurationsis also studied, providing insights into the design principles in context of potentialfabrication complexities. Further, the simulated Fano characteristic is validated againstthe theoretical value. The application of the proposed sensor is investigated for differenttypes of analyte such as chemical pollutants and temperature sensing.
