Abstract

In this work, an ultra-compact in-line fiber-optic Fabry-Perot interferometer is presented. The interferometric structure consists of a thin (<1 μm) amorphous silicon layer in line integrated into a standard single-mode optical fiber by means of an electric arc discharge technique. The device exhibits low loss (1.46 dB) and high interference fringe visibility (~30 % in linear scale) both in reflection and transmission due to the high refractive index contrast between silica and α-Si. A high linear temperature sensitivity up to 75 pm/°C is demonstrated in the range 15–52 °C. The proposed device is simple, compact, cost-effective, and attractive for point monitoring sensing application in ultra-high-temperature sensing in harsh environments.
