The effects of geometric parameters, metal film thickness, liquid refractive index, and optical material refractive index on polarization filtering and sensing characteristics are analyzed by the finite element method (FEM). The proposed PCF shows single-polarization filtering in communication window and has ultra-high corresponding bandwidth. At the 1.55 µm communication window band, the confinement loss of the y-polarized core mode is 819.27 dB/cm, while the x-polarized core mode is only 3.45 dB/cm. The crosstalk (CT) reached a maximum of 708.6 dB in the communication bands, and the corresponding bandwidth reaches 1000 µm when the fiber length is 1 mm. Meanwhile, the D-type PCF is widely used in sensing because it avoids filling the gold film and analyte in the internal pores. The change in the thickness of the mental coating from 39 nm to 22 nm provides the proposed PCF with sensing properties. By reducing the refractive index of fiber material, the maximum sensitivity is 10,741 nm/RIU. When the refractive index measurement range of the analyte is specified from 1.33 to 1.36, the average sensitivity reaches 7313 nm/RIU. Good performance enables the proposed compatible filtering and sensing PCF may be used in a wide range of scenarios.","PeriodicalId":13547,"journal":{"name":"Instrumentation Science & Technology","volume":"50 1","pages":"668 - 683"},"PeriodicalIF":1.6,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45077064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GeSe is an appropriate material for resolving this issue. According to the theoretical basis of the research, GeSe is a two-dimensional material which is a direct band gap semiconductor that may be utilized to promote electron transport and stimulate greater SPR phenomena. The first use of GeSe in an optical fiber sensor is reported in this study. A U-shaped optical fiber-GeSe-Au sensor is proposed. As a two-dimensional material with comparable physical characteristics to GeSe, MoS2 is compared to GeSe to characterize its influence upon the sensitivity. The sensitivity of fiber-GeSe-Au sensor is 7398.1 nm/refractive index unit (RIU), which is nearly twice as sensitive as a gold film SPR sensor and 1.5 times as sensitive as a sensor utilizing MoS2 nanosheets with the same structure. This study introduces a novel approach for enhancing the sensitivity, which gives a new option for monitoring biological substances at low concentrations with high sensitivity and stability and demonstrates that GeSe nanosheets have significant promise for future applications.","PeriodicalId":13547,"journal":{"name":"Instrumentation Science & Technology","volume":"50 1","pages":"577 - 588"},"PeriodicalIF":1.6,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45186157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strong photoelectric conversion of MoS2 and the wide forbidden band of h-BN are used to enhance the surface plasmon resonance of the gold film which greatly enhance the sensitivity of the sensor. The Au film was deposited on the optical fiber by controlled vacuum sputtering to monitor the thickness. The MoS2 nanolayer was deposited on the surface of the gold film by electrostatic adsorption and the hexagonal boron nitride nanolayer was subsequently superimposed to complete the preparation. The sensitivity of the prepared sensor was increased to 3803.0 nm/RIU, which is 71.5% higher than for the common gold film sensor. These results confirmed that this approach significantly upgraded the sensor performance.

It is a precise remote sensing technique that includes two or more bands in the visible and invisible spectrum. This study demonstrates the design and construction of a low-cost, multispectral imaging system using a single linear array sensor and a varifocal lens coupled to individual spectral band-pass filters. The system allows the automated data acquisition of raw spectral data for seven spectral bands, each with different wavelengths. The raw data are visualized in real-time to generate images of spectral bands to obtain the desired spectral information on the computer graphical screen. Sensor arrays with spectral responsivity between 0.3 and 1.05 μm and motorized filter disks with a linear guide are used for acquiring data from specific wavelengths. Axis movement of the imaging device is achieved by a linear guide for spatial monitoring. Seven different bands are scanned and transferred to the computer via motorized band-pass filter sets with the imaging device. The multispectral imaging device has high accuracy with a 0.9936 linear correlation coefficient (r2) and averaged noise of the total system is below 1% (0.7%). Although the present configuration uses seven spectral bands including visible and narrow bandpass optical filters to obtain multispectral information from an object, the system is designed to have a replaceable and selectable motorized rotating filter, easily remounted, and adjusted up to forty spectral bands with 20 nm full width at half maximum (FWHM).","PeriodicalId":13547,"journal":{"name":"Instrumentation Science & Technology","volume":"50 1","pages":"543 - 559"},"PeriodicalIF":1.6,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45684859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presented in this paper is a highly sensible SPR fiber sensor established on gold nanoparticle (AuNPs)/graphene oxide (GO) heterostructures and Au film coupling enhancement. The local electric field enhancement of the gold nanoparticle/graphene oxide heterostructure and gold film coupling, together with the sensitivity of the sensor, was analyzed using a finite element method. Theoretical results have provided evidence that this structure is efficient in enhancing the surface plasmon polariton (SPP) coupling, the local electric field, and the depth of electric field propagation outwards, while significantly improving the sensitivity of the sensor. Sensors with single- and double-layer gold nanoparticle/graphene oxide and enhanced Au film coupling were prepared with refractive index (RI) sensitivities of 2899.4 nm/RIU and 3436.2 nm/RIU, respectively, 37.92% and 63.46% higher than for conventional gold film sensors. Due to the chemical bonding of graphene oxide, the materials on the sensor have shown considerably robust interconnections, and the performance of the sensor remains almost unaffected after many measurements. Promising stability and reusability have been demonstrated, presenting favorable prospects for practical applications.","PeriodicalId":13547,"journal":{"name":"Instrumentation Science & Technology","volume":"50 1","pages":"530 - 542"},"PeriodicalIF":1.6,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41398734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
