Abstract
The invention covers a process of forming gratings in optical fiber. The gratings are formed at depth wherein the evanescent waves of the optical fiber are encountered. The process permits the fabrication of gratings in the optical fiber that reflect light of predetermined wavelengths. The grated optical fibers can be used as reflectors or interferometers when the gratings are used in pairs.
