研究目的
To study solitons in optical couplers made up from metamaterials using the exp(? Φ(ξ))-expansion scheme for four forms of nonlinearity.
研究成果
The paper successfully applies the exp(? Φ(ξ))-expansion scheme to recover singular and combo soliton solutions in optical couplers with perturbation terms, covering both twin-core and multiple-core couplers. The results are meaningful in optical couplers but do not represent a complete spectrum of soliton solutions.
研究不足
The exp(? Φ(ξ))-expansion scheme fails to recover bright and dark solitons in optical couplers, thus not representing a complete spectrum of soliton solutions.
