Spatiotemporal Optical Vortices with Transverse Orbital Angular Momentum

A dataset from figshare by Guangyu Fan, last updated on 2026-05-18. It contains data related to spatiotemporal optical vortices (STOVs) and their transverse orbital angular momentum (OAM). The work demonstrates programmable flux breathing and the use of these structures for free-space information transfer.

Use Cases

• Modeling spatiotemporal flux breathing based on the nonlinear mapping of the azimuthal phase gradient.
• Analyzing instantaneous group velocity anisotropy based on local phase gradient variations.
• Studying the reorganization of local OAM density into multilobed lattice structures.
• Developing encoding and decoding schemes for spatiotemporal topological states in free-space information transfer.

Strengths

• Dataset size is 191.5 MB, indicating a medium-scale collection of data.
• License is CC-BY-4.0, allowing for open sharing and adaptation.
• Includes both theoretical and experimental demonstration data as described in the summary.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
