“…In the following, we will investigate the influences of the structure parameters (d1, d2, d3, d4, and τ ) of the proposed SPR-PCF on the propagation characteristics when the analyte RI is chosen as 1.30, 1.35, and 1.40, respectively. For the proposed SPR-PCF, the structure parameters have great influences on the propagation characteristics, especially the central analyte-filled hole size and the first layer of air hole sizes [37][38][39].

“…Surface plasmon resonance (SPR) refers to an electromagnetic phenomenon, which is generated by the combination of free electron oscillations and a transverse magnetic polarized electromagnetic wave on the surface between dielectric medium and metal film [1,2]. Due to outstanding features such as label-free monitoring, high sensitivity, and realtime detection, as well as owning multifarious application such as environmental monitoring, medical diagnostics and food safety, polarization filters, and absorbers, SPR has achieved unprecedented progress in the realm of sensors [2][3][4]. Kretschman proposed a configuration of SPR sensor based on prism coupling [2,3,5].…”

Nowadays, plasmonic sensor based on photonic crystal fiber (PCF) attracted a great deal of attention in field of optical sensing. An opening up dual-core photonic crystal fiber based on surface plasmon resonance (SPR) are numerically demonstrated and analyzed for detecting wide refractive index (RI) range by Finite-Difference Time-Domain method (FDTD). The wavelength and amplitude integration methods, as well as figure of merit are used to investigate the sensor performance. For improving sensing performance, it is introduced a large hole between two cores in opening up section. The opening up section as a sensing channel is coated with gold film and a thin titanium dioxide (𝑇𝑖𝑂 2 ) layer. By surface engineering including imposing of grating on the gold film, specification of optimized values of different layers located near the surface, sensing performance are investigated. Next, the effect of the fiber structural parameters is analyzed to enhancing of SPR and fundamental core mode coupling. The proposed sensor revealed maximum wavelength and amplitude sensitivities of 15167 ( 𝑛𝑚 𝑅𝐼𝑈 ) and 207.19 (𝑅𝐼𝑈 −1 ), respectively. Due to ease of infiltering analyte and gold coating and tanks to high wavelength and amplitude sensitivity, the sensors can be promising candidate of physical and chemical sensing.

“…PCFs working under the principle of surface plasmon resonance (SPR) have a dominant sensing response with analyte refractive index changes. We have modeled PCF-SPR based sensors that utilize the different guiding mechanisms for EM light interaction with analytes [11]. The study shows a satisfactory sensing response for analyte index alterations.…”

In this paper, a polarization-maintaining single-mode rectangular-shaped hollow-core waveguide with four segmented air cladding in the terahertz (THz) regime is presented for detecting various toxic industrial chemicals. A new type of injection moldable cyclic olefin copolymer, commercially named as TOPAS is used as the base fiber material for its high optical transmission and high resistance to other chemicals. The finite element method with a perfectly matched layer as the boundary condition is employed for numerical explorations. The proposed sensor exhibits ultra-high relative sensitivity of 99.73% and ultralow effective material loss of 0.007 cm -1 at 1.6 THz frequency for Toluene in y polarization. This sensor also evinces a high birefringence of 4.16×10 -3 at 1.6 THz frequency. A maximum V parameter of 2.224 has been found at 2.2 THz which ensures the single-mode propagation of light. The sensor shows a very low confinement loss of 3.2×10 -11 dB/m and a high numerical aperture of 0.3574 at 1.6 THz frequency for Hydrogen Sulfide. This paper also concentrates on other important design parameters such as bending loss, mode field radius, beam divergence and effective area for serviceability of the sensor in the THz region. This sensor can be a very good candidate for various chemical detection as well as other applications in the terahertz regime.
