Femtosecond laser post-processing mechanisms for refractive index tuning of fiber Bragg gratings

Not Accessible

Your library or personal account may give you access

Abstract

We present an in-depth study on the evolution of the average refractive index profile of an inscribed fiber Bragg grating with respect to the femtosecond laser post-processing parameters. Herein, its influence on the spectral properties of the FBG is discussed.
