摘要：

We theoretically proposed the concept of temperature sensing using the soliton self-frequency shift (SSFS) effect in a fluorotellurite microstructured fiber (FTMF) which had one ring of six alcohol-infiltrated air holes. The glass material for the fiber core was 70TeO(2)-20BaF(2)-10Y(2)O(3) and the cladding AlF3-BaF2-CaF2-YF3-SrF2-MgF2-TeO2. Based on SSFS effect, temperature sensing in the mid-infrared (MIR) region was achieved by detecting the wavelength shift of solitons with the variation of temperature. Using a 2800 nm fiber laser with a pulse width of 131 fs as the pump light and a 0.5-m-long FTMF as the nonlinear media, the temperature sensing sensitivity could be as high as 2.09 nm/degrees C. To the best of our knowledge, this is the first study concerning temperature sensing in the MIR region by drawing on SSFS effect in a non-silica FTMF.
