Study on heat treatment of polarization-maintaining fibers
This paper primarily deals with the temperature characteristics of stress-induced high birefringence polarization-maintainting fibers (PMF). The heat treatment on the type of bow-tie PMF shows that its birefringence has increased by 46% after annealing, this result has been proved by the beat-length measurements before and after annealing.
