A pen-picture of optical solitons for the concatenation model with power-law of self-phase modulation by Sardar’s sub-equation method and tanh-coth approach

This work is about the retrieval of optical solitons for the concatenation model with power-law of self-phase modulation by the aid of Sardar’s subequation approach and its variation. The tanh-coth approach reveals the dark-singular straddled optical solitons solutions to the model. The parameter constraints for the existence of such solitons are also enumerated. Numerical simulations are also presented.
