Abstract
|
We report on the inscription of fiber Bragg grating in perfluorinated polymer optical fiber (CYTOP) by femtosecond pulses laser at 400 nm with phase mask technique and at 800 nm with two direct inscription methods: point-by-point and line-byline. We analyze the stability of the gratings after inscription and study their sensing properties. To discriminate between the properties of the CYTOP fiber and the influence of the over-clad, we consider gratings produced in CYTOP fiber with and without the over-clad, and we determine their sensitivities to temperature, humidity and strain.
