Here, the impact of angular misalignment and fiber overlap on the splicing loss, higher-order modes (HOMs) excitation, and polarization-dependent loss (PDL) of commonly-used AR-HCF with 5-nested tubes are comprehensively characterized. Simulation and experimental results reveal that the misalignment angle can introduce a maximum coupling loss of 0.12 dB while having almost no impact on HOMs excitation and PDL variation. Then, under the condition of perfect angular alignment, the parameter of fiber overlap during the splicing is optimized, and an average splicing loss of 0.05 dB over 10 times experiment is obtained, which is equivalent to the loss result of standard single mode fiber (SSMF) splicing. Spectral analysis shows that the normalized LP11 mode power has a slight increase from -31.62 dB to -28.33 dB, and the variation in PDL is less than 0.01 dB under the optimal fiber overlap of <inline-formula> <tex-math>$8~mu $ </tex-math></inline-formula>m, indicating that no structural deformation of AR-HCF thin tubes is introduced during the fusion splicing. Moreover, the mechanical robustness of the splicing is examined with a standard proof test returning a damage threshold of 250 gf @1 s. Our proposed fusion splicing technique can be extended to various AR-HCFs, providing the benefit of low-loss, robust, and repeatable interconnection between AR-HCFs.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 8","pages":"465-468"},"PeriodicalIF":2.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To take advantage of the curvature sensitivity of the MCM structure, the device needs to be placed in direct contact with the structure under analysis, the vibration produces periodical changes in the curvature of the fiber that in turns modulate the intensity of the attenuation band of the MCM transmitted spectrum. In order to characterize the response of the sensor, we first measured the vibration frequencies of a loudspeaker in the range of 500 to 12500 Hz observing a percentage relative error less than 0.5 %. Then, the sensor was placed in contact with an aluminum plate of 5 cm x 5 cm x 0.3 cm. It was possible to detect the frequency of several vibration modes of the plate in a very simple way. The curvature-sensitive MCM structure is simple, easy to build, and sturdy, these features make the device a good candidate for measuring mechanical vibrations of an object.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 8","pages":"457-460"},"PeriodicalIF":2.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor is fabricated by directly fusing a segment of ECF between two single-mode fibers (SMFs), forming a Mach-Zehnder interferometer (MZI) in an SMF-ECF-SMF structure. Due to the mode field mismatch between ECF and SMF modes, the fundamental mode of SMF is excited to higher-order modes and coupled into ECF to detect the external environment. The cores of the ECF present a <inline-formula> <tex-math>$2times 4$ </tex-math></inline-formula> arrangement, which can play the role of multipath MZI due to the existence of multiple cores. In the curvature detection, the maximum curvature sensitivity of the sensor can be up to −53.32 dB/m−1 within the curvature range of 0.3006 m−1–0.5483 m−1. A wavelength dip with a maximum extinction ratio of 22 dB is obtained in the transmission spectrum, which indicates that the ECF effectively equalizes light energy. In addition, the strain response is also measured. When the strain range changes from 0 to <inline-formula> <tex-math>$900~mu varepsilon $ </tex-math></inline-formula>, the maximum strain sensitivity is −1.83 pm/<inline-formula> <tex-math>$mu varepsilon $ </tex-math></inline-formula>.
