abstract = "A high-sensitivity Mach-Zehnder(MZ) interferometric refractive index(RI) sensor based on two different ultra-abrupt tapers is proposed and demonstrated experimentally. The whole fabrication process is relatively simple. One taper is fabricated by the fusion-splicing method and the ratio of the waist diameter to the taper length is 1:1. The other taper is fabricated by CO2 laser irradiation with a ratio around 1:10. According to the experimental results, the spectral loss of the proposed MZ interferometric sensor has a linear response to the external RI change with a ultrahigh sensitivity of -412.02138 dB/RIU(refractive index unit) in the range of 1.3505-1.3684. The sensor has the potential application for RI measurement in chemical or biochemical sensing fields due to its low cost, simple structure and extremely high sensitivity.",
