• To ensure continuous and efficient light coupling during WOW operation in a dynamic 3D environment.

Main Methods:

• Utilizing a spatial light modulator to encode diffractive phase patterns.
• Generating multiple, dynamic, diffraction-limited spots to track WOWs.
• Experimental testing for single WOW dynamic tracking and coupling.

Main Results:

• Successfully demonstrated dynamic tracking and coupling of light to a single WOW.
• Achieved effective coupling for both lateral and axial displacements.
• Validated the capability of dynamic diffractive techniques in maintaining light coupling.

Conclusions:

• Dynamic diffractive techniques provide a robust solution for maintaining light coupling to maneuvering WOWs.
• The proposed method enhances the operational efficiency and versatility of WOWs in 3D applications.
