By spinning the preform during the fiber drawing, it is possible to preserve circular polarization on Polarization Maintaining (PM) optical fibers that are originally highly birefringent.
Exail offers fibers for 1310 and 1550 nm applications with an optimized spinning rate to minimize the thermal and vibrational dependence of the output polarization.
Elliptical core design is available for low temperature dependence applications.
