Influence of Internal Stresses in Few-Mode Fiber on the Thermal Characteristics of Regenerated Gratings
The pre-treatment of few-mode fibers (FMFs) has been successfully done with CO2 laser. The wavelength difference, Δλ between the two resonant wavelengths in the few-mode fiber Bragg grating (FMFBG) varies with temperature increment during the annealing process. The results show that the treated fibe...
