There is provided a package for holding long-period fiber gratings formed on an optical fiber from which an outer coating is partially removed to form the gratings thereon. A recoating is then applied to the long-period fiber gratings to maintain the optical characteristics of the long-period fiber gratings, and thereafter a silica glass tube is fixed around the recoating to protect the long-period fiber gratings from an ambient environment.
