Abstract

This paper presents a novel, to the best of our knowledge, method for realizing soliton transformation between differ-ent potential wells by gradually manipulating their depths in the propagation direction. The only requirements for such a transformation are that the gradient of the manipulated depth is smooth enough and the solitons in different poten-tial wells are both in the regions of stability. The comparison of transformed solitons with the iterative ones obtained by the accelerated imaginary-time evolution method proves that our method is efficient and reliable. An interesting conse-quence is that in some complex potential wells in which it is difficult to find solitons by iterative numerical meth-ods, stable solitons can be obtained by the transformation method. The controllable soliton transformation provides an excellent opportunity for all-optical switching, optical infor-mation processing, and other applications.(c) 2023 Optica Publishing Group
