This powerful mathematical tool is applied to birefringent fibers with Kerr and parabolic laws of nonlinearity. Bright and singular soliton solutions are obtained along with respective constraints that must hold to guarantee the existence of these solitons. As a byproduct, singular periodic and doubly periodic solutions are also recovered from this algorithm.11311- 11325 PagesenAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/BirefringenceSolitonsExtended trial equation methodArticle
