Abstract
A process for creating a local high fiber birefringence and large variation in refractive-index modulation
with a polarization in fiber Bragg gratings using postwriting exposures with femtosecond pulses is presented. A
birefringence as high as ~8×10<sup>-4</sup> was obtained in
the core of SMF-28 fiber by exposing the cladding of the fiber in close proximity to the core/cladding interface
with a modulated multibeam interference field created by a phase mask. The birefringence is likely due to the
induced stress rather than the direct asymmetric refractive index modification.
