摘要
We present a novel and flexible helical-core fiber (HCF) SPR sensor with a double- layer deposition, which is fabricated by twisting an eccentric core fiber. By using the proposed MEP method, we obtain the RI sensing results of the HCF SPR sensor. Our results demonstrate that the resonance wavelength of HCF SPR sensor can be linearly controlled by changing the thickness of the high RI layer. Those characteristics enable the fabrication of sensor arrays in one helical single-core or multi-core fiber with several different twisting pitches for multi-parameter measurement.
