Abstract

Two kinds of self-loading Farby-Perot (F-P) fiber sensors were prepared by creating micro-grooves on side-face of single mode fiber-28 (SMF-28) and photonic crystal fiber (PCF) with 157 nm excimer laser. Self-loading F-P interference fringe shifts were measured under different temperature, stress and alcohol solution. Temperature sensing experiments show that the sensitivity of PCF and SMF F-P sensors are 0.0580nm/°C and 0.0535nm/°C when the temperature ranges from 30 °C to100 °C. The interference fringe shifts of PCF and SMF F-P sensors are 1.6 nm and 2.2 nm when they were loaded with 80 μm elongation along fiber axis, which correspond to stress sensitivity of 1.41pm/με and 1.50pm/με respectively. The interference fringe shifts of the SMF F-P sensor and the all-solid PCF sensor are 0.4775nm and 0.3490nm when the quality percentage of alcohol changes from 0 to 99.99%.
