| Summary: | The present paper examines analytically the Kaup-Newell equation, an important class of nonlinear Schrodinger equations with lots of applications in optical fibers. The Riccati equation approach is employed for the present study. The method is one of the recent active integration methods that transform the given partial differential equation to an ordinary one, and thereafter to algebraic equations. Various new optical soliton solutions are successfully disclosed by the method, including bright-singular, dark-singular, and singular optical soliton solutions to mention a few. Similarly, the constraint conditions involved are determined in relation to each soliton solution and illustrate some of the obtained solutions graphically. Finally, the present study can help in understanding many phenomena in optics in particular, and in mathematical physics in general. |
