Controlling the group velocity (v g ) of light is an important issue in order to understand light matter interactions and enable new technological applications. Surface plasmon polaritons(SPP) offer new possibilities in this regard. SPPs with small group velocities in the vicinity of the band edges of periodic structures and in metallic nano particle chains have recently been studied [1, 2]. In this report, we present the design, fabrication and realization of coupled plasmonic cavities using metallic Moire structures. The phase shifts at the nodes of Moire pattern enable localization of SPPs resulting in a mini band in the band gap region. We find group velocities around v g =0.44c at the center of the mini band and approaches to zero at the edges of mini band. |
