Highly influenced by filler materials with high refractive index
PBG fibers with high-index rods are very sensitive to such parameters as temperature and applied electric field.In order to obtain temperature sensing of photonic crystal fibers with high sensitivity
we propose a method
in which temperature-sensitive liquid is injected into the air holes of their claddings
and simulate the method by using the full vector finite element method.The results indicate that with the increase of temperature
the effective refractive index decreases
the mode field area increases
and the temperature sensitivity can be as high as 20.2dB/m/℃.
