A plasmonic Bragg reflector with rectangular-shaped transmission spectrum based on MIM (Metal-Insulator-Metal) waveguides is proposed and theoretically analyzed in this paper. As the MIM waveguide structure is treated as a cascade structure of multi-F-P cavities and by use of Transfer Matrix Method (TMM), the property parameters of the reflector is related to the structure parameters of grating, so that the performance index of reflector can be optimized. As an example, a wide bandgap reflector is designed by this method, the center-wavelength of it at 1550nm, the full width at half maximum (FWHM) of it at 640nm and the center-transmission of it approaching zero.
