Research of the Interference of Surface Plasmon in an Enhanced Two-Slit Structure

Abstract:

A modified two-slit structure is provided to investigate surface plasmon (SP) interference. It’s based on a novel structure, implemented by adding a metal film on the input port of the T-shape slit. The affection of metal film for SP interference is investigated by simulation. Results show that the interference phenomenon can be more obvious with the metal film II than without it. With our structure, the added metal film can enhance transmission energy of SPs and improve interference effect. The results will give a theoretical guidance for development of nano-scale photonics devices.
