Abstract (EN): A fiber optic sensor for simultaneous measurement of refractive index and temperature is presented. The sensing probe is achieved by introducing multimode interference inside a high birefringence fiber loop mirror resulting in a configuration capable of refractive index and temperature discrimination. The multimode interference peak is sensitive to the surrounding refractive index (90 nm/RIU) and slightly responsive to the temperature (0.005 nm/degrees C). On the other hand, the birrefringent fiber loop mirror is highly sensitive to temperature (2.39 nm/degrees C) and has no response to refractive index. Therefore, a temperature independent refractive index measurement can be made with a resolution of +/- 2.5x10(-5).
