Abstract

This paper analyses the effect of the waist diameter on the sensitivity of different sensors based on non-adiabatic multicore fiber couplers. The sensors have been evaluated for high-temperature and strain measurements. A homogeneous 7-core multicore fiber has been used to fabricate three different coupler sensors based on the tapering technique, using a special CO2 laser splicer. The waist length for all cases is 60 mm, while the studied waist diameters are 20 mu m, 40 mu m, and 60 mu m. We report that the central core exhibits sensitivities of 62.1 pm/degrees C and -5.2 pm/mu epsilon for temperature and strain, respectively. The evaluated high-temperature range is from 100 degrees C to 600 degrees C, and the strain range is from 0 mu epsilon to 3333 mu epsilon. Based on our findings regarding the evaluated waist diameters, we observed that the multicore fiber coupler with a waist diameter of 20 mu m exhibits a large sensitivity to strain variations. Conversely, the sensor with a waist diameter of 60 mu m demonstrates better sensitivity for temperature measurements. Additionally, we have used fan-in/fan-out optical devices to enable individual access to each core. This allowed us to extend our study and conduct sensitivity analysis in the outer cores.
