Popis:	The fabrication is reported of a simple, compact, and stable refractive index (RI)-independent temperature sensor based on a soft glass fiber (SGF) interferometer. Because the SGF has a high thermal expansion coefficient and a high RI, it is sensitive to temperature change but not sensitive to the RI change of liquids with lower RI. It thus can be used to detect the temperature change of aqueous solutions accurately. As an example, a temperature sensor with a temperature sensitivity of ~7 pm/°C and a negligible RI sensitivity of only about -1 nm/RIU (RI unit) in the range 1.32-1.43 is demonstrated. In addition, our SGF interferometer has potential applications and advantages in detecting liquids such as liquid crystals with higher RI.
