Abstract
A precise method for modifying the birefringence of stress-induced high-birefringence (Hi-Bi) fiber is demonstrated by side polishing a Panda-type fiber with a maximum polished length of at least . The polishing depth is controlled with an accuracy of by piezoelectric ceramic microdisplacement. The accuracy of the birefringence is of the order of . This method allows high-quality Hi-Bi fiber segments to be conveniently implemented with low loss at any desired birefringence between and in our experiment from one stress- induced Hi-Bi fiber and without changing the directions of the stress axes. The finite-element method is used to simulate the procedure, and the numerical results agree with the experiment.
