Surface plasmon microcavity for resonant transmission through a slit in a gold film
Bibliographic record
Abstract
We demonstrate the use of a compact surface plasmon (SP) microcavity formed in a 300 nm thick gold film to resonantly enhance the optical transmission through a subwavelength slit. Focussed ion beam milling is used to create 200 nm deep SP microcavities, with widths between 800 nm to 1300 nm, each with a 180 nm slit in its center. The experimentally-measured TM polarized optical transmission has a wavelength-dependent peak that has similarities with finite-difference time-domain calculations in terms of peak-position and enhancement factors of peak transmission. The calculations show, by observing the near-field distributions, the interaction between the SP microcavity standing waves and the slit to create enhanced transmission. The SP microcavity demonstrated here is easily fabricated and may be optimized for future applications in surface-enhanced Raman scattering, nonlinear optics and surface plasmon resonance sensors.

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.
