Abstract

We propose a micro Fabry-Perot cavity fabricated by chemical etching a microstructure fiber. The microstructure fiber we use is an all silica endless single-mode fiber, whose core is surrounded by a group of air holes. A suspended core in the cladding can be created by removing the surrounded air hole usinghydrofluoric acid. The sensing head is fabricated by splicing a short section microstructure fiber with single mode fiber and submit the fiber end to chemical etching. The temperature sensitivity of the proposed sensor is 14.3pm/°C.
