Popis:	In this study, we propose and simulate in the NIR region a tunable stop-band filter based on an MIM waveguide coupled to a triangular cavity. The transmission spectra of the filter are obtained using the R-Soft CAD software based on the two-dimension (2D) finite-difference time-domain (FDTD) method, which uses perfectly matched layers (PML) to absorb the outgoing energy fields. A stop-band plasmonic filter with a large bandwidth and high bandpass transmission is achieved by adding another triangular cavity resonator. One can also control the range filtered and the shift of the central wavelength by tuning the second triangular cavity parameters. This structure has important applications in highly integrated photonic circuits.
