A Novel Temperature-Insensitive Package for Fiber Bragg Grating

摘要

An innovative temperature-insensitive metal package for Fiber Bragg grating (FBG) was designed to compensate the effect of temperature. The wavelength shift of FBG was tested with the new package and without the package,rnrespectively. In the range of -20°C~100°C, the temperature sensitivity of the FBG was 1.7 pm/°C with the new packagernand 10.7 pm/°C without the new package, respectively. It shows that the new package for FBG can eliminate thernwavelength shift with the temperature change. So it is suitable to use the FBG with the new package as an optical filter.
