Energy optimization of diffraction managed accessible solitons

Abstract

We present the generation, stability analysis, and energy optimization of diffraction managed accessible breather solitons in highly nonlocal nonlinear media comprising an array of alternately positive and negative diffracting media. The system has been modeled using a nonlocal nonlinear Schrödinger equation and solved both analytically and numerically. The initial beam energy for the diffraction managed solitons has been determined and tabulated for a large range of both local and average diffraction. At comparatively higher diffraction values, the diffraction managed system requires significantly less energy for soliton formation than in a constant diffraction system, while it requires a little more for lower diffraction values. Naturally, an intermediate diffraction value offers the energy matching point for diffraction managed and constant diffraction systems, which in turn eases the use of both systems in a single network if necessary. The diffraction managed system requires less tuning of initial beam energy for soliton formation, and it is more prominent for negative average diffraction. The diffraction managed accessible solitons show a variety of bifurcations. They are robust against randomness in diffraction and/or nonlinearity.
