Effect of different liquid and filling modes on thermo sensitive characteristics of photonic crystal fibers
By using different methods to fill different types of thermo sensitive liquids
the thermo sensitive characteristics of a high birefringent Photonic Crystal Fiber(PCF) based on hybrid lattices was researched. The relationship of birefringence properties and temperature was investigated using Comsol software in finite element method. The numerical results show that the thermo sensitive characteristics of the PCF are influenced by liquid types and filling methods. When the ethanol is filled in the circular air holes in a core area
the sensitivity of the PCF worked at an excitation wavelength of 1 550 nm is up to 2.5×10
-5
/℃ with pitch of holes in 1 μm
the diameter of a circular air hole in 0.96 μm and the aspect ratio of rectangular air holes in 4. As compared with that of corresponding PCF structures
the fiber proposed and liquid filling method have higher thermo sensitivity and broader application prospects for high sensitivity temperature sensors.
