This work addresses Thirring optical solitons in birefringent fibers. The dynamics of the vector coupled nonlinear Schrödinger equation, which describes the propagation of Thirring solitons through birefringent optical fibers with spatio-temporal dispersion and Kerr law nonlinearity, is investigated analytically. The tools of integration applied in this dynamical model are the Jacobian elliptic equation expansion approach, Riccati equation expansion scheme and soliton ansatz method. These algorithms lead to exact Thirring bright, dark and singular solitons along with the corresponding parameter constraints.
