Abstract
In this paper, we will study the propagation properties of nonlinear periodic waves (PW) in a fiber optics for the coupled nonlinear Schrodinger equation with parabolic law with weak non-local nonlinearity (CNLSE-PLWNLNL). We will find the chirped periodic waves (CPW) by using some Jacobi elliptic functions (JEF) and also obtain some solitary waves (SW) like dark, bright, hyperbolic, singular, periodic and other solitons. The resultant chirp associated with each of these optical solitons (OS) will be observed dependent on pulse intensity. The graphical representation of these waves will also be presented.
