Abstract

A method is provided for securing an optical fiber Bragg grating to a retaining element having a helical groove. In accordance with the method, an optical fiber Bragg grating is wrapped around the retaining element so that the optical fiber Bragg grating extends in and along the helical groove. Next, an excess length of the optical fiber Bragg grating is provided in the helical groove to substantially alleviate tension exerted upon the optical fiber Bragg grating. Finally, the first and second ends of the fiber Bragg grating are affixed to the retaining element.
