Abstract: This article reports the basic transmission line characteristics of metal-insulator-metal (MIM) wave guiding structure, design of band pass and band stop filter using a high resonance step impedance resonator (HRSIR). The effective refractive index, propagation length and characteristic impedance of the MIM wave guiding structure are obtained through full wave simulation. The proposed design of band pass and band stop filters operates simultaneously at optical frequency bands at 185.72 THz and 230.02 THz. The variation of designed plots are used to determine appropriate geometric parameters of each step when filter specification is given. Hence, the designed filters open a new way for the designing of integrated photonic devices based on surface plasmons.
