“…Bragg reflectors are fabricated by alternatively stacking two kinds of dielectrics in metal-insulatormetal (MIM) or insulator-metal-insulator (IMI) plasmonic waveguides [12], and can realize the filtering functions. The IMI waveguide gives rise to less loss for the longer propagation distance, but fails to confine a light into subwavelength scale and, thus, is not suitable for high optical integration [14]. The MIM waveguide has a strong confinement of light and acceptable propagation length for SPPs [12].…”

A novel and simple plasmonic filter based on metal-insulator-metal plasmonic waveguides with a nanodisk resonator is proposed and investigated numerically. By the resonant theory of disk-shaped nanocavity, we find that the resonance wavelengths can be easily manipulated by adjusting the radius and refractive index of the nanocavity, which is in good agreement with the results obtained by finite-difference time-domain (FDTD) simulations. In addition, the bandwidths of resonance spectra are tunable by changing the coupling distance between the nanocavity and waveguides. This result achieved by FDTD simulations can be accurately analyzed by temporal coupled mode theory. Our filters have important potential applications in high-density plasmonic integration circuits.

“…In recent years, several types of plasmonic sensors, based on the metal-insulator-metal (MIM) or insulator-metal-insulator (IMI) con gurations, have been proposed and investigated [7][8][9]. The IMI structures support the well-known long-range SPPs (LRSPPs) waveguide modes with relatively low propagation loss, which in turn can improve the sensing accuracy [10]. However, they cannot realize the subwavelength eld localization, limiting the improvement in sensitivity.…”

A novel design for a highly-sensitive plasmonic sensor, consisting of metal-insulator-metal (MIM) waveguide with a coupled split-square-ring resonator, is presented and studied by two-dimensional (2D) finite-difference time-domain (FDTD) method in this paper. The simulation results show that the proposed sensor possesses a refractive index (RI) sensitivity up to 2040 nm/RIU with optimized structural parameters. In addition, a temperature sensitivity of −1.2 nm/◦C is determined. Numerical calculations indicate that the sensing performance can still be further improved via optimization of the structure. The compact waveguide structure may find important applications in areas of sensing and integrated circuits.

“…13,14) Over the past decades, the SPP in noble metals has been widely studied. In particular, great effort has been focused on developing various plasmonic Bragg reflectors including the insulator-metal-insulator (IMI) 15,16) and metalinsulator-metal (MIM) [17][18][19][20] structures, which are both realized by alternately stacking dielectric materials of different thicknesses or permittivities to produce the desired effective index contrast on the surface of the metals. Because of the difficulty in controlling the permittivity functions of metal, the functionalities of the metallic plasmonic devices are constrained to some extent.…”

We propose and numerically analyze a Bragg reflector composed of periodically arranged graphene nanoribbon waveguides with different widths. Because of the unique property of the graphene edge mode, the effective index contrast used for the reflector can be obtained by designing graphene nanoribbons with different widths without changing the dielectric substrate structure. Good band stop filtering characteristics are shown at the band gap of the transmission spectrum by numerical simulation. The performance of the proposed Bragg reflector is analyzed in terms of different parameters, such as the chemical potential, the number of periods, and the size of the unit cell. The proposed Bragg reflector will be expected to have important potential applications in the highly integrated SPP-based photonic devices.
