Abstract
The invention provides a process for forming a fiber keeping a circular polarization and a device for implementing this process. This process consists, during drawing and twisting of the fiber from a formable material source, in remelting on the surface a part of the volume of said fiber in a zone where it is subjected to twisting stresses.
