A temperature-compensated material of fiber Bragg grating (FBG), which has negative thermal-expansion coefficients, has been presented. The temperature coefficient of FBG's center wavelength is less than 0.0005nm/°C after three-layers-structure package under tension. For the first time, PMD of temperature-compensated FBG have been detailedly studied. The PMD of temperature-compensated FBG has been measured from -20°C to 60°C. The measured result shows that the PMD has little changed at different temperature.
