Integrated Wide-Band Power Divider/Combiner at Plasmonic Interfaces
Bibliographic record
Abstract
We propose a wide-band power divider/combiner configuration to facilitate light access and manipulation in planar nano-plasmonic devices. Light is incident from a standard silicon nanowire (negligible propagation losses) to be accessed by a nano-plasmonic circuit providing subwavelength confinement. The structure circumvents the inherent losses associated with long distance light propagation in nano-plasmonic splitters as coupling and splitting are performed at the same interface with small splitting losses. Plasmonic slot waveguides (PSWs) are utilized for subwavelength confinement. Two PSWs placed orthogonally to a silicon nanowire are utilized for the power division/combining functionality. The power splitter has been analyzed by the finite-difference time-domain numerical method. The proposed device is of compact size and wide-band operation. The relative displacement of the silicon nanowire from the PSWs is optimized. A splitting of 34%, over most of the wavelength spectrum from 0.8-2.5 μm , is demonstrated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
