✦ Synopsis

The e ect of friction in ferrules on compression tuning characteristics of ÿber Bragg gratings (FBG) was observed and analyzed in this paper. It was demonstrated that the micro-bending of the ÿber in the ferrule would cause friction between ÿber and inner wall of the ferrule, and the friction would make a non-uniform strain in the FBG and degradations of its re ection spectrum. To avoid the e ect, some measures have been applied including reducing the ferrule diameter to ÿt the ÿber, and ÿlling some lubrication in the ferrule, and so on. Near 10 nm tuning range can be obtained with good spectral performance.
