Linear mode coupling (LMC) in ultrafast fiber lasers creates deformable vector solitons (VSs). Weak LMC yields heteronuclear VSs, while strong LMC generates homonuclear VSs with unique "caterpillar" motions.
Area of Science:
- Nonlinear optics
- Ultrafast photonics
- Fiber laser technology
Background:
- Vector solitons (VSs) are localized structures in nonlinear systems.
- The impact of intermodal linear coupling on VS properties is not well understood.
Purpose of the Study:
- Investigate the influence of linear mode coupling (LMC) on vector soliton dynamics.
- Explore novel VS patterns and their potential applications in ultrafast optical sources.
Main Methods:
- Utilized an ultrafast fiber laser as an experimental platform.
- Predicted and demonstrated the effects of LMC on VS temporal and spectral structures.
Main Results:
- Linear mode coupling induces deformable vector solitons.
- Weak LMC results in heteronuclear VSs (dissimilar polarization modes).
- Strong LMC leads to homonuclear VSs with 'caterpillar' motions.
Conclusions:
- LMC significantly alters vector soliton characteristics.
- New VS patterns are discovered, offering versatile ultrafast optical source possibilities.
