The discovery of the soliton is considered to be one of the most significant
events of the twentieth century. The term soliton refers to special kinds of waves
that can propagate undistorted over long distances and remain unaffected even
after collision with each other. Solitons have been studied extensively in many
fields of physics. In the context of optical fibers, solitons are not only of fundamental
interest but also have potential applications in the field of optical fiber
communications. This thesis is devoted to the theoretical study of soliton pulse
propagation through single mode optical fibers.Cochin University of Science and TechnologDepartment of Physics, Cochin University of Science and Technolo
