Abstract
A novel compact temperature sensor based on a fiber loop mirror (FLM) combined with an alcohol-filled highlybirefringent photonic crystal fiber (HiBi-PCF) is proposed and experimentally demonstrated. The output of the FLM is an interference spectrum with many dips, of which the resonant wavelengths are quite sensitive to temperature because the interference of the FLM is sensitive to the optical path difference due to the refractive index change of the filled alcohol. Experimental results show that the temperature sensitivity reaches up to 5.42nm/°C for a 6.3cm long alcoholfilled PCF used in the FLM.
