Abstract
We propose and demonstrate a Fabry-Perot fiber-optic tip sensor for high-resolution refractive-index measurement. The sensor head consists of a short air cavity produced near the tip of a single-mode fiber by 157-nm laser micromachining. The external refractive index is determined from the maximum visibility of the interference fringes in the reflection spectrum of the fiber. This sensor provides temperature-independent measurement of practically any refractive index larger than that of air and offers a refractive-index resolution of ∼4× 10-5 in its linear operating range. The experimental data agree well with the theoretical results.
