Beam evolutions of solitons in strongly nonlocal media with fading optical lattices

Abstract

We address the impact of imprinted fading optical lattices on the beam evolution of solitons in strongly nonlocal nonlinear media. The results show that the width of the soliton experiences a change with the increasing propagation distance, the critical power for the soliton varies with the lattice fading away, and the soliton breathing is affected by the initial lattice depth and the nonlocality degree.

The mobility of nonlocal solitons in fading optical lattices

“…In this paper, we study the soliton mobility in nonlocal nonlinear media with an optical lattice that fades away exponentially along the propagation direction. We consider the following dimensionless nonlocal nonlinear Schrödinger equation (NNLSE) [14,15] with a fading optical lattice [16]…”
