Paper Abstract

A sensing configuration of the fiber taper intrinsic Fabry-Perot interferometer (FTIFPI) was presented and developed. Direct inscription method of intrinsic Fabry-Perot interferometers in optical fiber tapers with a femtosecond laser has been fabricated experimentally. Fabry-Perot interferometers are firstly realized in the waist of fiber tapers. The experimental results indicate that the change in wavelength has a good linear relationship with temperature, while the fringe visibility keeps the same approximately. In the range of 0°C~100°C, the interference spectrum sensitivity is 12pm/°C. The fringe visibility decreases linearly with the liquid refractive index increasing, while extremes keep the same approximately.
