Abstract: A method of producing an optical grating component including only a single continuous grating field formed in a longitudinal waveguide rib, the method including the steps of defining a grating in an optic chip including a portion thereof through which the longitudinal waveguide rib is to extend, and then defining the lateral edges of the longitudinal rib in the optic chip, whereby any portion of the grating extending laterally beyond the lateral width of the rib is removed in the step of defining the lateral edges of the rib leaving a single continuous grating field that has straight lateral grating boundaries that are laterally aligned with the straight lateral edges of the rib.
