Spin–Orbit-Engineered Selective Transport of Photons in Plasmonic Nanocircuits with Panda-Patterned Transporters
Bibliographic record
Abstract
The spin–orbit coupling of light, which can be utilized to manipulate the polarization and spatial degrees of freedom of photons, has shown unprecedented potential in realizing on-chip integrated nanocircuits and quantum information processing. Particularly, this chiral coupling mechanism can result in unidirectional transport of spin-dependent light at a subwavelength scale by designing specific nanostructures. Here we propose and demonstrate a dielectric-loaded plasmonic nanocircuit with a panda-patterned transporter to directionally couple and guide plasmonic waves through two-branched waveguides. Both simulation and experimental results reveal that the waveguide modes excited by circularly polarized light with different spin states can be selectively coupled to one of two branching waveguides, with a measured unidirectionality efficiency up to 0.95. The proposed configuration may open up more possibilities in developing multifunctional nanocircuits that could be utilized for exploiting chiral manipulation with flexible 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
