Numerical demonstration of mid-infrared temperature sensing by soliton self-frequency shift in a fluorotellurite microstructured fiber

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 70TeO2–20BaF2–10Y2O3 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...
