- 摘要: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 LP0,21 and LP0,22. The third one is the
result of the coupling between the higher-order core mode LP02 and cladding mode LP0,29 or LP0,30. These resonant
wavelengths shift in different direction with the increasing temperature, and the experimental results show their
temperature sensitivity are 66.54pm/℃,90. - 合写作者:Jie Dong, Mei Sang*, Qiuli Wang, Chenhao Zhong，Tiegen Liu,
