Abstract
A fiber temperature sensor with high sensitivity based on a Michelson interferometer is realized by fusion-splicing a peanut-shape structure in single-mode fiber (SMF). The theory and experimental results show that the peanut-shape structure can couple the light energy of the core mode into the cladding and re-couple the light in the cladding into the core. A high-quality interference spectrum with a fringe visibility of about 18 dB is observed. Experimental demonstration shows that the device can be heated up to 900 °C with a sensitivity of about ∼0.096 nm/°C. The device has the advantages of low-cost, high sensitivity and easy fabrication, which makes it attractive for sensing applications.
