Abstract

A simple technique for correcting systematic phase errors introduced during the holographic inscription of fibre Bragg gratings is presented. The technique involves characterising the fabrication errors associated with the phase mask and writing medium (i.e. the fibre). This is accomplished by measuring the phase of the coupling coefficient of a weak, uniform dasiatrace gratingdasia written in the fibre. This phase is then used to generate a phase-corrected profile by combining the inverse of the measured phase with the phase of a target gratingdasias profile. The trace grating is then overwritten with the stronger phase-corrected grating. Using this technique, a dual phase-shifted grating has been fabricated successfully and the overall phase error in reduced by a factor of 13.
