Dark, singular and straddled optical solitons in birefringent fibers with generalized anti-cubic nonlinearity

This paper enumerates optical soliton solutions in birefringent fibers having generalized form of anti-cubic law of refractive index. The unified Riccati equation expansion yields dark, singular as well as solitons that are straddled between dark and singular ones. A few additional solutions emerge from the integration scheme as a byproduct. (C) 2020 Elsevier B.V. All rights reserved.
