In this paper, influence of InP coupling cavity (height H2) on Fano resonance of sub wavelength MIM waveguide was studied by FDTD. It was observed redshift of the resonance peaks of mode mj (j=1, 2, 3) with H2 increase and the resonant wavelengths of mode mj (j=1, 2, 3) were a function of the height H2. Before and after the addition of air cavity, the relative farfield intensities I was a function of height H2. Therefore, InP as discrete state would be used as the filling dielectrics of Fano resonance in the MIM waveguide.
