Abstract
•Optical solitons in magneto-optic waveguides are studied.•Dual-power law nonlinearity is considered.•Solutions are obtained in terms of Jacobi's elliptic functions.•The limiting approach, when modulus of ellipticity approaches unity, yielded soliton solutions.
This paper applies new ϕ6 model expansion scheme to obtain solitons in magneto–optic waveguides that come with dual–power law nonlinearity. Initially, the solutions are in terms of Jacobi's elliptic functions. Upon approaching the limiting values of the modulus of ellipticity, bright, dark and singular solitons emerge. The existence criteria of such solitons are also presented.
