Exact optical solitons in (n + 1)-dimensions under anti-cubic law of nonlinearity

In this article, the first time, exact optical solitons with (n + 1)-dimensional nonlinear Schrödinger equation have been constructed under anti-cubic law of nonlinearity that describes the propagation of light pulses in optical fibers. The integration criteria that is adopted was (G′/G)-scheme. As a result, the dark and singular optical solitons are extracted in (n + 1)-dimensions. Additionally, the constraint conditions for the existence of these solutions are also listed. However, this scheme fails to retrieve the bright soliton.
