A high sensitivity measurement method for temperature has been proposed and investigated based on an isopropanol-filled photonic crystal fiber long period grating (PCF-LPG). Due to the high thermo-optic coefficient (TOC) of isopropanol, the sensitivity of the proposed temperature sensor could be effectively improved by filling isopropanol in the air waveguides of PCF. It can be found that the resonant...
In this paper, according to the refractive index of magnetic fluid variation relationship with temperature, the transmission characteristics of photonic crystal fiber (PCF) filled with the magnetic fluid (MF) were simulated and analyzed using the full-vector finite element method. The major researches were numerical simulation about the temperature affects on the mode field, transmission mode, the...
