Abstract
In accordance with the invention, an optical fiber is provided with a metal coating of controlled variable thickness by the steps of disposing the fiber in position for receiving coating metal from a metal source, and depositing metal while moving a shadow mask between the fiber and the source to provide patterning of deposited metal. Advantageously, the mask is translated at a constant velocity perpendicular to the fiber. The method is particularly useful for the fabrication of adjustable Bragg gratings.
