Polarization-maintaining optical fiber

OverviewDesignsPolarization crosstalkPrinciple of operationApplications

Several different designs are used to create birefringence in a fiber. The fiber may be geometrically asymmetric or have a refractive index profile which is asymmetric such as the design using an elliptical cladding as shown in the diagram. Alternatively, stress permanently induced in the fiber will produce stress birefringence; this may be accomplished using rods of another material included within the cladding. Several dif
