Polarization mode dispersion effects in embedded fiber optic strain sensors
نویسندگان
چکیده
The strain of an optical fiber, embedded in a composite laminated plate, was measured using radio frequency iiiterferometery. 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 ofpolarization mode dispersion associated with excess fiber birefringence, which was introduced during the manufacturing process of the laminated plate.

Polarization Mode Dispersion in Radio-Frequency Interferometric Embedded Fiber-Optic Sensors
The effect of fiber birefringence on the propagation delay in an embedded fiber-optic strain sensor is studied. The polarization characteristics of the sensor are described in terms of polarization mode dispersion through the principal states of polarization and their differential group delay. Using these descriptors, an analytical expression for the response of the sensor for an arbitrary inpu...

متن کاملSolutions to the dynamical equation of polarization-mode dispersion and polarization-dependent losses
We study the evolution of optical signals in single-mode optical fibers in the presence of polarization-mode dispersion and polarization-dependent losses. Two geometric vectors on the Poincaré sphere are defined to characterize the effects of polarization-mode dispersion and polarization-dependent losses on the optical field in the fiber. By solving the dynamical equation for these two vectors,...
