“…The benefits of MIM structures are low loss, longer diffusion length, and broad subwavelength confinement, relative to pure photonic structures [45]. Furthermore, the low footprint MIM design and easy production and integration [43] allow it to be the ideal candidate for numerous optical applications such as optical splitters [9], filters [6,20] switches [23], logical gates [13,35], demultiplexer [36], perfect plasmonic absorbers [30,47], and optical sensors [10,41].…”

In this paper, a high-sensitive plasmonic sensor based on metal-insulator-metal waveguide coupled with the interesting metal nanoracetrack defects in a cross cavity is proposed and investigated. The sensing characteristics of the proposed design are analyzed by the means of finite difference time domain method which is embedded in the commercial simulator R-Soft. The positions of transmission peaks can be easily manipulated by adjusting both the radius and the distance between the centers of the two racetrack defects in the cavity. The achieved results exhibit a linear relationship between the material's refractive indices and theirs corresponding wavelengths of resonance, whereas the obtained maximum linear sensitivity is 3410 nm/RIU which corresponds to a sensing resolution as precise as 2.93 × 10 −6 RIU. The proposed sensor has great impact on different technologies advancement as it can be implemented in high performance nanosensors and bio-sensing devices.

In this work, different structures are designed based on graphene square-nanoring resonator (GSNR) and simulated by the three-dimensional finite-difference time-domain (3D-FDTD) method. Depending on the location and number of graphene nanoribbons (GNR), the proposed structures can be utilized as a band-pass filter, wavelength demultiplexer, or power splitter in the mid-infrared (MIR) wavelengths. The tunability of the suggested assemblies is easily controlled by changing the dimensions and/or the chemical potential of the GSNRs.Benefiting from the nanoscale and ultra-compact GNRs, these structures can be proposed as basic blocks for optical computing and signal processing in the MIR region.

“…However, the midinfrared region has not been fully researched and utilized compared with other bands because very few materials inherently respond to mid-infrared [3]. Recently, the merging of surface plasmon polaritons (SPPs) and graphene-based metamaterials open a way for controlling and manipulating mid-infrared waves and mid-infrared devices [4]- [6]. Studies have shown that graphene-based metamaterials can excite SPPs waves from mid-infrared to THz band [4], [7].…”

“…In recent years, various filters based on graphene periodic structure have been proposed theoretically and experimentally. For instance, graphene-supported metamaterials [13]- [15], graphene-based band-stop filter [3], [16], [17], multi-channel graphene-based absorber [18], [19] and so on. These filters have been greatly improved in performance compared with previous structures.…”

Wide-Range Tunable Narrow Band-Stop Filter Based on Bilayer Graphene in the Mid-Infrared Region

et al. 2020

View full text Add to dashboard Cite

In this paper, a tunable graphene-based band-stop filter in the mid-infrared region was demonstrated, which consists of periodic structure based on bilayer graphene nanoribbons. Due to the unique tunable Fermi level of graphene, the resonance wavelength of the filter can be tuned over a wide range (10020 nm-15100 nm) with the applied voltage varying from 1 V to 5 V, realizing selectivity and tunability. The results also confirm that the presented structure can realize a narrow-band selective filter with a 3 dB bandwidth of 40 nm. Furthermore, the trough transmittance of stopband is close to zero and the transmittance of passband remains above 96.7%. Moreover, this filter is quite robust to the incident angles. The stopband is still extremely narrow as the incident angle varies from 0°to 60°, realizing wide-angle filtering. In addition, the fabrication processing and fabrication error tolerance are investigated, and it has proved that the filter is quite tolerant to fabrication deviations. Hence, the work has potential applications in narrowband filters, active plasmonic switches, and sensors in the mid-infrared region.
