In nonlinear optics, the interplay of lattice potentials and nonlinearity can support soliton formation, yet the effects of inverted cubic-quintic terms remain underexplored. The authors demonstrate that this inverted setting supports stable, sharp solitons in one and two dimensions, offering potential applications as bit pixels in photonic data processing.
