Abstract

Using both an approximation and numerical simulations, we examine solitons in a dual-core nonlinear optical fiber in which the Raman effect acts. We find that the Raman effect restabilizes the symmetric soliton at large energies. It also allows quasi-stable asymmetric solitary waves to exist at smaller energies.
