Four hybridized modes result from mode hybridization between surface plasmon polariton Bloch wave modes on the two gratings are observed. By changing the dielectric environment, mode hybridization behavior can be manipulated. Importantly, waveguide-plasmon polariton mode due to hybridization between grating supported surface plasmon polariton Bloch wave mode and cavity supported waveguide mode is observed. We demonstrate that surface plasmon polariton Bloch wave mode and Fabry-Perot cavity mode with the same mode symmetry can interact by presenting an anticrossing behavior, which can be controlled by laterally shifting one grating with respect to the other that causes a phase difference shift of the two involving modes. The proposed plasmonic cavity offers potentials for subwavelength lithography, tunable plasmonic filter, and controllable light-matter interaction.
