The extended auxiliary equation approach recovers the full spectrum of solitons. Additionally, solutions in terms of Weierstrass’s elliptic functions are reported. The results are all presented with the necessary parameter constraints that naturally emerge from the scheme. KW - soliton KW - dispersion KW - birefringence ER -
