“…The technology of coating the inside of microstructured fibers with a metal layer is mature [40][41][42]. We can use the method of sputtering the gold layer from the micro-structured fibers side [43] or thermal gold layer evaporation at the micro-structured fibers end [44] to coat gold films in the inner of nested elliptical tubes. The gold-coated HC-ARF can be fabricated through the next steps.…”

A multi-mode polarization-filtering hollow core anti-resonance fiber whose cladding is composed of four circular tubes and four elliptical tubes is demonstrated. In the vertical directions, two small nested elliptical tubes are coated with gold films in the inner wall. This fiber can filter x-polarized LP01, LP21 and LP02 modes in different wavelengths through surface plasmon resonance which, is produced by two gold films. The polarization extinction ratio of LP01, LP21 and LP02 modes can reach 293, 116 and 30 at the wavelength of 1550 nm, 1570 nm and 1574 nm, respectively. We can adjust the polarization-filtering operation wavelength by changing the ellipticity of elliptical tubes in the cladding. Thus, this fiber can achieve polarization-filtering operation in the whole C and L bands.

“…Zhang et al achieved selective air hole coating with metal by suction and evaporation of metal nanoparticle mixtures [29]. In addition, metal coated PCFs have been reported with fabrication techniques including sputtering [30], electroless plating [31], and thermal evaporation for tapered PCFs [32]. Though it remains a challenge to maintain uniformity and thickness of the metal coating inside and outside of the PCFs for sputtering and evaporation techniques, better uniformity of metal layers was achieved using chemical deposition methods with more complicated conditions, e.g., high pressure or high temperature [3].…”

Designing Highly Sensitive Surface Plasmon Resonance Sensor With Dual Analyte Channels

et al. 2021

The ease of controlling waveguide properties through unparalleled design flexibility has made the photonic crystal fiber (PCF) an attractive platform for plasmonic structures. In this work, a dual analyte channel's highly sensitive PCF bio-sensor is proposed based on surface plasmon resonance (SPR). In the proposed design, surface plasmons (SPs) are excited in the inner flat portion of two rectangular analyte channels where gold (Au) strip is deposited. Thus, the surface roughness that might be generated during metal deposition on circular surface could be effectively reduced. Considering the refractive index (RI) change in the analyte channels, the proposed sensor is designed and fully characterized by the finite element method based COMSOL Multiphysics software. Improved sensing characteristics including wavelength sensitivity (WS) of 186,000 nm/RIU and amplitude sensitivity (AS) of 2,792.97 RIU −1 in the wide RI range of 1.30 to 1.43 is obtained. In addition, the proposed sensor exhibits excellent resolution of 5.38 × 10 −7 , signal to noise ration (SNR) of 13.44 dB, figure of merits (FOM) of 2188.23, detection limit (DL) of 101.05 nm, and detection accuracy (DA) of 0.0204 nm −1 . Outcomes of the analysis indicate that the proposed sensor could be suited for accurate detection of organic chemicals, bio-molecules, and biological analytes.INDEX TERMS plasmonic, bio-sensor, photonic crystal fiber, finite element method, detection lmimit

“…Its unprecedented properties [2][3][4] are from an arrangement of very tiny and closely spaced air holes going through the whole length of fiber, which makes it possible to overcome many limitations intrinsic to standard optical fibers, especially in fiber sensing field. Many fiber sensors based on PCFs were fabricated by novel way recently such as femtosecond laser drilling [5], acid microdroplets etching [6], and gold coating [7]. The principles are similar with conventional fiber sensors including Mach-Zehnder interference [5,[8][9][10], Michelson interference [11,12], and multimode interference [13,14].…”

An experimental investigation on an S-tapered photonic crystal fiber interferometer is presented in this paper. The sensor exhibits highly surrounding refractive index sensitive, which is 4.7 × 10 −3 RIU (refractive index unit) in 1.33-1.39 and 1.45 × 10 −3 RIU in 1.39-1.44 commensurable with general sensors. Attribute to the S-shape's distortion, red shifts are measured in axial strain test. In addition, insensitivity (4.3 pm/°C) in low temperature and sensitivity (22.4 pm/°C) in high temperature are confirmed by experiments. These properties combined with a simple fabrication process and a durable structure.
