چکیده :

A new Metal–insulator–metal (MIM) waveguide structure with a square resonator and ring resonator cavity for a plasmonic band stop filter is proposed. Its operation is explored using the method of finite difference in time domain (FDTD) analysis and simulation. A set of detailed analysis of the structural parameters, such as waveguide and resonator dimensions, is done to delineate how these parameters modify the transmission characteristics. The simulations reveal that, with a cavity width of 50 nm, the filter exhibits an impressive quality factor of 218 at the resonance wavelength of 1134 nm, outperforming previously reported comparable designs. Moreover the minimum transmittance estimated values at the wavelengths of 1186 and 1134 are 15% and 17%, respectively. This filter demonstrates high performance and has various applications in the design of optical integrated circuits where precise light filtering is required.
