A novel sensing peak identification method for high accuracy refractive index (RI) sensing is proposed. The implementation takes the intensity of interference maximum as the characteristic to distinguish interference peaks, tracking the sensing peak continually during a RI changes, with high measurement accuracy and simple computation. To verify the effect of the method, the extrinsic Fabry–Perot interferometer (EFPI) sensor has been fabricated using the large lateral offset splicing technique. In the RI range from 1.346 to 1.388, the measurement range of the EFPI with the proposed method reaches at least 6 times larger than that of EFPI with the wavelength tracking method and the largest measurement error is −4.47 × 10−4. The EFPI refractive index (RI) sensor identified the sensing peak is believed to play an important role in RI, concentration and density sensing, etc., for superior performance.

Optical fiber sensors of refractive index play important role in analysis of biological and chemical samples. This work presents a theoretical investigation of a spectral response of fiber optic microsphere with zinc-oxide (ZnO) thin film deposited on the surface and evaluates the prospect of using such structure for refractive index sensing. Microsphere is fabricated by optical fiber tapering method on the base of a single mode fiber. A numerical model is described and simulation was conducted to assess the influence of the ZnO layer deposition on a reflected signal. The results indicate that ZnO film improves the performance in terms of a potential application in refractive index sensor. Full Text: PDF ReferencesY. Qian, Y. Zhao, Q. Wu, Y.
