Abstract
A solution for implementing gratings with optical sources where polarization-maintaining fiber is required or desirable utilizes polarization-maintaining fiber between the grating and the optical source. The grating, however, is actually written in regular, or non-polarization-maintaining fiber. The polarization-maintaining fiber is spliced to the non-PM fiber. Since this splice exists in the commercial components, it can be performed in laboratory conditions.
