“…For integrated metaphotonic systems, plasmonic transparency windows in the transmission spectra of the systems, around the plasmonic resonance of the cavities, have been demonstrated either by mode hybridization or through the plasmonic analogue of EIT [ 32 , 33 , 34 ]. A large majority of these works use non-symmetric nanocavities integrated to plasmonic waveguides [ 32 , 35 , 36 , 37 , 38 ], or by exciting localized surface plasmons (LSP) of non-symmetric metallic nanoparticles excited with the evanescent field of guided modes [ 39 , 40 ].…”

In this contribution, we numerically demonstrate the generation of plasmonic transparency windows in the transmission spectrum of an integrated metaphotonic device. The hybrid photonic–plasmonic structure consists of two rectangular-shaped gold nanoparticles fully embedded in the core of a multimode dielectric optical waveguide, with their major axis aligned to the electric field lines of transverse electric guided modes. We show that these transparencies arise from different phenomena depending on the symmetry of the guided modes. For the TE0 mode, the quadrupolar and dipolar plasmonic resonances of the nanoparticles are weakly coupled, and the transparency window is due to the plasmonic analogue of electromagnetically induced transparency. For the TE1 mode, the quadrupolar and dipolar resonances of the nanoparticles are strongly coupled, and the transparency is originated from the classical analogue of the Autler–Townes effect. This analysis contributes to the understanding of plasmonic transparency windows, opening new perspectives in the design of on-chip devices for optical communications, sensing, and signal filtering applications.

“…Currently, different types of SPP reflectors have been developed, including those with a Bragg structure, [13][14][15] T-shape structure, [16][17][18] and microcavity structure. [19] For Bragg structure, the reflection can be realized by periodic change of the cladding layer material, the insulator width or material.…”

A new type and easy-to-fabricate metal–insulator–metal (MIM) waveguide reflector based on Sagnac loop is designed and investigated. The transfer matrix theoretical model for the transmission of electric fields in the reflector is established, and the properties of the reflector are studied and analyzed. The simulation results indicate that the reflectivity strongly depends on the coupling splitting ratio determined by the coupling length. Accordingly, different reflectivities can be realized by varying the coupling length. For an optimum coupling length of 750 nm, the 3-dB reflection bandwidth of the MIM waveguide reflector is as wide as 1.5 μ m at a wavelength of 1550 nm, and the peak reflectivity and isolation are 78% and 23 dB, respectively.
