Abstract

A method is provided for precise and repeatable location of one or more Bragg gratings (20) in a large diameter optical waveguide (14) having a cross-section of at least about 0.3 millimeters, featuring the steps of: defining a reference location on a fixed placement datum (16) narranged on a waveguide fixture device (10); defining one or more desired locations on a large diameter optical waveguide arranged on the waveguide fixture location in relation to the reference location; and writing one or more Bragg gratings in the large diameter optical waveguide at the one or more desired locations based on the reference location on the fixed placement datum. The step of defining the reference location may include marking the fixed placement datum with a scribe mark thereon; and securing the fixed placement datum in a groove (12) in a waveguide fixture device.
