摘要：
A simple sensor for simultaneous measurement of refractive index and temperature in solutions based on fiber Bragg Dating (FBG) is proposed The sensor contains only a not mal FBG with a pigtail fiber When the FBG is immersed in different liquids of refractive index, the side mode suppression ratio of the FBG varies due to the Fresnel reflection of the pigtail fiber The sensor is also capable of simultaneous measurement refractive index and temperature combining the thermo-optic effect of the FBG Its ease of fabrication and low-cost offer the attractive applications in chemical and biological sensing (C) 2010 Elsevier B V All lights reserved
