Abstract:
1. A method, comprising: moving a photosensitive material doped optical waveguide relative to an interference pattern generator at a speed and/or at a period associated with a profile of a Bragg grating; while moving the photosensitive material doped optical waveguide relative to the interference pattern generator at the speed and/or at the period associated with the profile of the Bragg grating, moving the photosensitive material doped optical waveguide and the interference pattern generator in discrete increments along a longitudinal axis of the photosensitive material doped optical waveguide; while moving the photosensitive material doped optical waveguide relative to the interference pattern generator at the speed and/or at the period associated with the profile of the Bragg grating and while moving the photosensitive material doped optical waveguide and the interference pattern generator in discrete increments along a longitudinal axis of the photosensitive material doped optical waveguide, moving an ultraviolet (UV) light pulse source in discrete increments along the longitudinal axis of the photosensitive material doped optical waveguide; and while moving the photosensitive material doped optical waveguide relative to the interference pattern generator at the speed and/or at the period associated with the profile of the Bragg grating, while moving the photosensitive material doped optical waveguide and the interference pattern generator in discrete increments along a longitudinal axis of the photosensitive material doped optical waveguide, and while moving the ultraviolet (UV) light pulse source in discrete increments along the longitudinal axis of the photosensitive material doped optical waveguide, exposing the photosensitive material doped optical waveguide to an ultraviolet (UV) light pulse from the ultraviolet (UV) light pulse source through the interference pattern generator when the photosensitive material doped optical waveguide and the interference pattern generator are effectively stationary with respect to each other and the ultraviolet (UV) light pulse source is effectively stationary with respect to the effectively stationary photosensitive material doped optical waveguide and interference pattern generator combination.
