Abstract
Abstract The manipulation of spin-related photons is crucial for developing next-generation integrated circuits. However, the spin-orbit interaction of light is typically very weak at nanoscale due to the diffraction limit. Here, a dielectric-loaded plasmonic nanocircuit is proposed, utilizing a chiral cylindrical structure, to directionally couple and guide plasmonic waves through dual-branch waveguides. Optimized results reveal that the waveguide modes excited by circularly polarized light with different spin states can be selectively coupled to one of the two targeted branch waveguides, with a calculated unidirectional coupling efficiency as high as 0.95. The proposed structure could provide avenues for realizing on-chip integrated nanocircuits and developing advanced multifunctional nanocircuits with enhanced degrees of freedom.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
