A novel and simple multi-wavelength band-pass filter based on metal-insular-metal (MIM) waveguide with different nanodisk cavity is proposed and investigated numerically by Finite-Element-Method (FEM) simulations. According to resonant theory of nanodisk, multi-wavelength band-pass filter can be achieved for different wavelength. It also shows that the transmission characteristics of the filter and the resonant wavelength can be easily manipulated by changing the gap between nanodisk and straight waveguide or changing the radius of the nanodisk. This kind of plasmonic waveguide filter may become important promising application in highly plasmonic integrated circuits.
