Abstract :
Under the guidance of the coupled mode theory, we take some mode simulation to the cone area of LPFG produced through melting the cone method. Measured LPFG resonance wavelength curve at different temperatures, find the temperature sensitivity is 62.8pm/°C when temperature below 200°C, and the resonance peak drift and temperature changes in the basic of a linear relationship.
