The strain of an optical fiber, embedded in a composite laminated plate, was measured using radio frequency interferometery. While the response of a similar fiber glued to the plate was linear with the applied loading, the strain experienced by the embedded fiber exhibited significant fluctuations around the linear expected trend. This phenomenon is qualitatively described in terms of polarization mode dispersion associated with excess fiber birefringence, which was introduced during the manufacturing process of the laminated plate.
