Abstract

During the past two decades, strong coupling of SPPs with other excitations, such as localized surface plasmons in nanostructured metals and excitons in semiconductor dots has been the subject of intensive studies [1]. Controlling the coupling of SPPs in plasmonic systems is one of the most interesting and important issues in plasmonics to find potential applications such as biosensors and waveguides. In this work, we study the mutual coupling of SPPs in the metal-insulator-metal (MIM) structure and demonstrate the anti-crossing behavior experimentally and theoretically.
