ABSTRACT:
A method and system for the controlled irradiation of optical fibers in a process for fabricating optical fiber components such as Bragg grating devices. A beam of ultraviolet light is passed through a narrow slit in a mask to form a narrow beam of light. The narrow beam is focused into a line image that is directed onto the optical fiber to produce a photo-induced refractive index change in the optical fiber. The intensity and configuration of the line image as it impinges the optical fiber is controlled to reduce detrimental effects to the fiber.
