Some general periodic solutions to coupled nonlinear Schrodinger equations

Exact travelling wave periodic solutions of a pair of coupled nonlinear Sch rodinger equations are obtained in terms of the Weierstrass elliptic g-func tion. These solutions which are of one and the same functional form describ e, in particular, two novel classes of bounded periodic and solitary wave s olutions of considerable physical interest, while previously known bounded periodic and solitary wave solutions turn out to be just special cases of t hem.
