Independently tunable dual resonant dip refractive index sensor based on metal-insulator-metal waveguide with Q-shaped resonant cavity
文献摘要：
A plasmonic resonator system consisting of a metal-insulator-metal waveguide and a Q-shaped resonant cavity is proposed in this paper.The transmission properties of surface plasmon polaritons in this structure are investigated by using the finite difference in time domain(FDTD)method,and the simulation results contain two resonant dips.The physical mechanism is studied by the multimode interference coupled mode theory(MICMT),and the theoretical results are in highly consistent with the simulation results.Furthermore,the parameters of the Q-shaped cavity can be controlled to adjust the two dips,respectively.The refractive index sensor proposed in this paper,with a sensitivity of 1578 nm/RIU and figure of merit(FOM)of 175,performs better than most of the similar structures.Therefore,the results of the study are instructive for the design and application of high sensitivity nanoscale refractive index sensors.
