Abstract

A waveguide may be translated relative to the optical system that creates the grating in the waveguide. Phase errors that arise from the writing process may be corrected by appropriate translations of the waveguide relative to the system that creates the grating. In some embodiments, the waveguide may be translated relative to a phase mask used to write a grating into the waveguide.
