Abstract
An optical fiber is stressed along its axis with a strain of at least 1% while light is introduced transversely to write a grating. The strain increases the photosensitivity of the fiber and reduces the time required to write the grating. Alternatively, the fiber can be compressed radially and inwardly, or compressed along its axis.
