In this paper we have designed and analyzed step impedance resonator based ultra wide-band (UWB) band pass filter using plasmonic MIM waveguide. The UWB band pass filter has been designed by introducing a shot-circuited stub to implement the shunt inductance between two quarter wavelength (λ/4) step impedance resonators. There is a strong coupling between the stubs. The plasmonic UWB band pass filter has been designed at E band (1360-nm to1460-nm) optical wavelength. The band width of plasmonic ultra wide-band band pass filter is very effective compared to narrow-band band pass filter. The reflection and transmission characteristics, variation of reflection and transmission coefficents by varying the dimensions of UWB, field distribution of plasmonic UWB has been realized using full wave simulation by using commercially available CST microwave studio software. The UWB band pass filter can further used for the development of photonic integrated circuits (PICs).
