Optical filter assisted by surface plasmon resonance

Abstract

One of the multilayer films consists of both metallic and dielectric thin films at subwavelength is called metal-insulator-metal (MIM) structure. An appropriate illumination condition of light for the surface has a chance to induce surface plasmon resonance (SPR), and the resultant spectroscopic phenomenon is interesting. In this study, we have started to simulate the phenomena and to do some basic experiments. The study objective is to develop a novel optical filter for optical communications.
