Theory and experimental observation of programmable nonreciprocal solitons

Key Points

• This research aims to create and demonstrate programmable nonreciprocal solitons that can adjust their propagation speed based on coupling strength.
• Developed a new actively nonreciprocal coupling system for solitons.
• Theoretical modeling was performed alongside experimental measurements.
• Investigated the impact of coupling strength on soliton propagation speed.
• Demonstrated the ability to achieve stable and unidirectional propagation of topological solitons.
• Found that soliton speed significantly depends on the strength of nonreciprocal coupling.
• Exhibited programmable control over the dynamics of soliton speed in lossy media.
