Abstract :
This paper presents the time analysis of the Bragg wavelength shift in fiber gratings based on the elastodynamics theory. The model is valuable for estimating an upper limit for the tuning speed when traction forces are applied to the free end of the grating. A comparison between the single-mode silica optical fiber and polymer optical fiber is performed, showing the differences in time response, tuning speed, and Bragg wavelength shift when the same longitudinal load is applied on both types of fibers.
