$Polarization-maintaining fiber refractive index measurement$

Polarization-maintaining fiber refractive index measurement

The proposed method retrieves refractive indices of PM optical fibers using adaptive algorithms and interferometry. Employing a Mach-Zehnder interferometer, the method accurately analyzes optical phase differences in PM fibers. It is difficult for manufacturers to specify a polarization extinction ratio (PER) for light output by polarization-maintaining (PM) fibers, since this parameter depends on the length of the fiber, how it is routed, and the polarization and alignment of the input light.
