title: Increase of photosensitivity in Ge-doped fibers under strain.
abstract: Straining a Ge-doped optical fiber increases its UV photosensitivity. The speed of grating fabrication in a standard AT&T telecommunication fiber increases by 18 times, while the final refractive-index change is enhanced by a factor of 5. Measurements reveal opposite changes in the stress of the fiber core induced by UV light in strained and unstrained fibers.
