“…More focus in this paper was on signal transmission for different ports. Of course, this mechanism can be used for switching or filtering, which is tailored to each specific frequency range for output port (Amoosoltani 2020;Moradian et al 2020a, b;Mozaffari and Farmani 2019;Farmani et al 2018Farmani et al , 2020aFarmani and Mir 2020;Hamzavi-Zarghani et al 2019;Sadeghi et al 2019;Baqir et al 2019;Ghodrati et al 2019;Ji et al 2020). Also as mentioned above, we have to a filter in the through input which has all the input frequencies except, the frequencies that resonate in the ring resonator.…”

In the advanced plasmonics integrated circuits (PICs) there has been outstanding, continuing interest in developing routers to harness light-matter interactions in nanoscale dimensions with wanted optical properties. In this regard, herein, we introduce an all-optical router based on nanometer ring resonator which surface plasmon resonance (SPR) and nonlinear materials are used simultaneously to enhance high performance range. By changing the radius of the ring resonator and the intensity of the light we achieved control of the parameters and the routing. The results of routing and shifting the central frequency with light intensity and radius of the ring resonator are studied. The performance of the router indicates that a ring is required for each ports, which changes the control parameters to change its central frequency, as well as we can be said the use of switches and filters as other design features. These routers have advantages such as nano scale size, low light intensity, fast response time, integratable and etc., which are highly used in all-optical circuits, image processing and today's modern technology. In our simulation, we consider transmission or reflection of light in each ports based on the finite difference time domain (FDTD).

“…One of the most significant nanoparticles is graphene. In 2004 graphene flakes were isolated by Andre Giem and Konstantin Novoselove ( Farmani and Mir, 2020 , Farmani et al, 2020 , Farmani et al, 2020 , Ghodrati et al, 2020 , Hamzavi-Zarghani et al, 2019 , Han et al, 2020 ). The lightest known material with a two-dimensional structure has improved biosensors application in terms of its outstanding properties like high mobility, strong structure, high conductivity, transparency, and high capability to drug delivery and loading.…”

“…Gas detection through surface plasmon resonance (a kind of plasmonic sensor) was first observed in 1982, eventhough its commercial development is still very limited. Plasmonic sensors are not only limited to gas sensing but also are widely used in various applications such as pressure sensing [8], chronic diseases detection caused by bacteria [9], terahertz absorption [10,11], pesticides analysis [12],new biomaterials detection like ether, ethyleneglycol, chlorobenzene, and quinoline [13], street light controlling [14], lab on chip application like spectroscopy and sensing application [15] etc. Particular gas molecules absorb IR light at a certain wavelength (also called as characteristic wavelength) [16], which are proportional to the gas concentration.…”

This work mainly focussed on the sensing of the environmentally damaging gas carbon dioxide (CO 2 ) by designing a gas sensor based on a surface plasmon resonance (SPR) principle. The proposed model is based on the metal-insulator-metal (MIM) model which mainly relies on metal thickness, dielectric thickness, and incident light wavelength. A comparative analysis between conventional as well as MIM-based structure is shown in this study and it is observed that by operating at 4400 nm incident light wavelength,the MIM-based structure shows sharp resonance curve, high resolution, minimum FWHM, and extremely high FOM. By using the modified Elden's formulae, the variation in refractive index is investigated by changing the numerical values of humidity, temperature, pressure, and CO 2 content from the reference value, respectively. For each case, the sensitivity has been estimated. By using the proposed MIM-based structure, FOM value as high as 1273.11RIU −1 ; at the end of this article, limit of detection (LOD) is calculated by varying the CO 2 gas concentration.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
