For this study, a temperature sensor utilizing a novel tellurite photonic crystal fiber (PCF) is designed.In order to improve the sensor sensitivity, alcohol is Pênfigo foliáceo canino: estudo retrospectivo de 43 casos clínicos e terapia (2000-2005) Canine Pemphigus foliaceus: a retrospective study of 43 clinical cases and therapy (2000-2005) filled in the air holes of the tellurite PCF.Based on the degenerate four-wave mixing theory, temperature sensing in the mid-infrared region (MIR) can be achieved by detecting the wavelength shift of signal waves and idler waves during variations in temperature.Simulation results show that at a pump wavelength of 3550 nm, the temperature sensitivity of this proposed sensor can be as high as 0.70 nm/°C.

To the best of our knowledge, this AbundanceR: A Novel Method for Estimating Wildlife Abundance Based on Distance Sampling and Species Distribution Models is the first study to propose temperature sensing in the MIR by drawing on four-wave mixing (FWM) in a non-silica PCF.
