1Influence of Internal Stresses in Few-Mode Fiber on the Thermal Characteristics of Regenerated Gratings显示文摘The pre-treatment of few-mode fibers (FMFs) has been successfully done with CO2 laser The wavelength difference, AA 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 fibers with lower stresses have lower thermal sensitivity in △λ than that of non-treated fiber. However, the treated fibers produce FMFBGs with better thermal durability and regeneration ratio. It is conceived that the presence of those stresses in the pristine fiber is responsible for the high thermal sensitivity in △λ. The thennal relaxation of stresses and structural rearrangement during the thennal annealing process are responsible for the degradation of the strength and resilience of the regenerated grating.Nurul Asha MOHD NAZAL Kok Sing LIM Yen Sian LEE Muhammad Aizi MAT SALIM Harith AHMAD 2019Photonic Sensors2019,9,2:1
