Abstract

A LPFG with a period of 145μm has been successfully inscribed in the few modes fiber (FMF) by CO₂ laser-irradition method. The mode coupling theory indicates that the first two resonant wavelengths of the LPFG attribute to the mode coupling between the core mode LP₀₁ and the cladding modes LP_0,21 and LP_0,22. The third one is the result of the coupling between the higher-order core mode LP₀₂ and cladding mode LP_0,29 or LP_0,30. These resonant wavelengths shift in different direction with the increasing temperature, and the experimental results show their temperature sensitivity are 66.54pm/°C,90.36pm/°,115.1pm/°, respectively
