Dynamically Controlled High-Efficiency Vortex Beams with Skyrmion Textures via a Bilayer P

Simulation data for optical vortex and skyrmion beam generation using a bilayer photonic-crystal slab platform. The dataset likely contains parameters and results from temporal coupled-mode theory (TCMT) modeling, created by Letian Meng and published on figshare in May 2026. It includes results for transmission-type vortex beams with up to 81% efficiency and reflection-type beams reaching 94%.

Use Cases

• Optimizing photonic crystal slab designs for vortex beam generation based on efficiency metrics.
• Analyzing the interplay between bound states in the continuum (BICs) and Fabry–Pérot resonances for tunable emission.
• Modeling dynamic control of transmission and reflection channels via spacing modulation.
• Generating full Poincaré beams with skyrmion textures for applications in precision measurements.

Strengths

• Includes specific efficiency metrics: transmission-type vortex beams up to 81% and reflection-type up to 94%.
• Describes a novel platform enabling dynamic control through spacing modulation.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (1.9 MB), potentially indicating limited scope or number of simulation runs.
