Abstract :
A fiber sensor for simultaneous measurement of refractive index (RI) and temperature in solutions based on multimode interference is presented. The intensity and the wavelength of the interference minimum will vary with the RI and the temperature of the solution, respectively. The sensitivity of the RI and the temperature are 94.58 dB/RI and 0.0085 nm/°C, respectively. Its ease of fabrication and low-cost offer the attractive applications in chemical and biological sensing.
