Abstract

We consider a coherently coupled nonlinear Schrodinger equation with modulated self-phase mod- ¨
ulation, cross-phase modulation, and four-wave mixing nonlinearities and varying refractive index
in anisotropic graded index nonlinear medium. By identifying an appropriate similarity transforma�tion, we obtain a general localized wave solution and investigate their dynamics with a proper set of
modulated nonlinearities. In particular, our study reveals different manifestations of localized waves
such as stable solitons, Akhmediev breathers, Ma breathers, and rogue waves of bright, bright-dark,
and dark-dark type and explores their manipulation mechanism with suitably engineered nonlinearity
parameters. We have provided a categorical analysis with adequate graphical demonstrations.
