“…Especially, the microwave transmission line was proposed to characterize the transmission properties of MIM stub waveguides [7]. Liu et al [82] developed the transmission line theory for lossless waveguide, which can easily obtain the transmission and dispersion properties. Successively, Pannipitiya et al [83] proposed an improved transmission model for dissipative MIM waveguides with stub structures.…”

Plasmonic waveguides that allow deeply subwavelength confinement of light provide an effective platform for the design of ultracompact photonic devices. As an important plasmonic waveguide, metal-insulator-metal (MIM) structure supports the propagation of light in the nanoscale regime at the visible and near-infrared ranges. Here, we focus on our work in MIM plasmonic waveguide devices for manipulating light, and review some of the recent development of this topic. We introduce MIM plasmonic wavelength filtering and demultiplexing devices, and present the electromagnetic induced transparency (EIT)-like and Fano resonance effects in MIM waveguide systems. The slow-light and rainbow trapping effects are demonstrated theoretically. These results pave a way toward dynamic control of the special and useful optical responses, which actualize some new plasmonic waveguide-integrated devices such as nanoscale filters, demultiplexers, sensors, slow light waveguides, and buffers. for SPP propagation. The unique features of MIM waveguides can be utilized to realize nanoscale photonic functionality and circuitry [11]. In this review, we mainly focus on our research about the manipulating properties in the MIM plasmonic waveguides. Due to the limit of this small topic, an amount of research in the plasmonic field will be omitted, for example, the important applications of SPPs for the enhancement of nonlinear effects [12], beam focusing [13,14], polarization analyzer [15], optical amplifier [16], and so on. We review some recent development of MIM plasmonic waveguide devices. Especially, plasmonic wavelength filtering and demultiplexing have been introduced. The analogue of electromagnetic induced transparency (EIT) and Fano resonances and their applications are presented in the MIM plasmonic waveguide systems. The slow light and rainbow trapping in the MIM waveguides are demonstrated. These results may provide some useful information for attracting researchers' interests in further investigation of the control of light and its applications in the plasmonic waveguides.

“…Periodic gratings introduced on metallic surfaces can lead to PBGs as SPPs propagate along the metallic surfaces. These structures have been used to manufacture plasmonic Bragg reflectors [7,8], SPP mirrors, beam splitters [9][10][11], and SPP filters. SPP waveguide filters, which are of great importance in modern optical communication, have been theoretically proposed and experimentally demonstrated, such as tooth-shaped nanoplasmonic waveguide filters [12][13][14], filters based on long-range SPPs [15], channel drop filters [16,17], ring resonators [18], and band-pass filters with nanodisk resonators [19].…”

2013) Tunable narrow band filter based on a surface plasmon polaritons Bragg grating with a metal-insulator-metal waveguide, Journal of Modern Optics, 60:15, 1217-1222, A tunable narrow band filter based on a Bragg grating with surface plasmon polaritons is developed and investigated numerically by using the finite-difference time-domain method. A defect state with narrow transmission peak (about 15 nm) is shown to appear in the bandgap by introduction of a defect into the Bragg grating, which can thus be used as filtering device. We also show that double-channel filtering can be realized by introducing two defects into the Bragg grating. The resonant wavelengths in the bandgap are related to the position of defects and the refractive index of the insulator. Our results may provide useful information in the design of tunable narrow band filters in nano-circuits.
