Abstract
A method of manufacturing optical identification elements that includes forming a diffraction grating in a fiber substrate along a longitudinal axis of the substrate. The grating includes a resultant refractive index variation. The method also includes cutting the substrate transversely to form a plurality of optical identification elements that have the grating therein along substantially the entire length of the elements. Each of the elements has substantially the same resultant refractive index variation.
