Based on coupled‐mode theory for LP modes, spun four‐lobe stress region fibers are theoretically analyzed. It is indicated for the first time that there are not any birefringence in spun four‐lobe stress region fibers if four lobes are symmetrically placed around the fiber axis. The same result is valid for spun fibers with eight‐lobe and 16‐lobe stress region, both having zero birefringence. © 2007 Wiley Periodicals, Inc.
