Abstract
A method and apparatus for generating single polarization fiber laser output are disclosed. A Bragg grating is non-destructively fabricated within the fiber to introduce differential loss between the two polarizations of the laser output. Curvature at the grating site into a tight loop further increases the differential loss between the available polarizations.
