AN INVESTIGATION ON FIBER OPTICAL SOLITON IN MATHEMATICAL PHYSICS AND ITS APPLICATION TO COMMUNICATION ENGINEERING
free download

Abstract Solitons are self-localized wave packets arising from a robust balance between dispersion and nonlinearity. Soliton is the physics of wave, acting upon wave. In mathematics and physics, a soliton is a self-reinforcing solitary wave that maintains its 

Subcarrier Multiplexing Using DACs for Fiber Nonlinearity Mitigation in Coherent Optical Communication Systems
