摘　　要：In this paper,we experimentally demonstrated the application of the Au-nanocoated twisted single-mode fiber(Au-TSMF)structure for the response of the multiparameter.Firstly,we fabricated an Au-TSMF,which achieved high sensitivity to refractive index(RI)and torsion.Additionally,based on the theory of polarization interference,we amplified its polarization sensitivity and induced the phase factor caused by polarization as a wavelength shift.Ultimately,we achieved the response of the Au-TSMF structure to the multiparameter,which had the sensitivity of-0.436 dB/(deg/m)for clockwise torsion,-0.156 dB/(deg/m)for anticlockwise torsion,0.3915 nm/rad for the left-handed circularly polarized state,-0.926 nm/rad for the right-handed circularly polarized state,and-692.9 dB/RIU for RI.Due to the advantages of the all-fiber integrated system,this work holds great potential for facilitating fiber optic integrated devices for optical fiber biosensors and biomedical diagnostic applications.
