Abstract

A novel temperature sensor by using photonic bandgap (PBG) effect is demonstrated. The solid core photonic bandgap fiber (PBGF) with infiltrated high refractive index solution is used for temperature measurement. Two high index solutions were infiltrated with refractive index of 1.58 and 1.64. It shows that the rising photonic bandgap edges of PBGF have a blue shifting. The 112.40nm shifting was observed with 1.58 refractive index oil infiltrated when the ambient temperature was changing from 24°C to about 65°C. The better sensitivity of the temperature measurement 2.74nm/°C was achieved.
