Optical solitons with anti-cubic nonlinearity using three integration schemes

This paper employed three integration schemes to obtain soliton solutions in optical fibers with anti-cubic nonlinearity. These are traveling waves, tanh-coth scheme and finally the modified simple equation method. These yielded bright solitons, singular solitons, dark singular combo solitons and other waves. The existence criteria for these solitons are presented. The paper concludes with a discussion on conservation laws. (C) 2017 Elsevier Ltd. All rights reserved.
