Abstract

We report a miniaturized inline Fabry–Perot interferometer directly fabricated on a single-mode optical fiber with a femtosecond laser. The device had a loss of $16\mathrm{dB}$ and an interference visibility exceeding $14\mathrm{dB}$. The device was tested and survived in high temperatures up to $1100°\mathrm{C}$. With an accessible cavity and all-glass structure, the new device is attractive for sensing applications in high-temperature harsh environments.
