Multiple surface gratings on azopolymers for generating surface plasmons
Bibliographic record
Abstract
Surface relief gratings are optically inscribed on azobenzene polymer films. Multiple gratings can be inscribed on the same spot either simultaneously or sequentially by projecting a holographic pattern onto the surface. The grating pitch can range from 350 nm to 1.5 μm and depths can easily reach 400 nm. The inscription is done at room temperature, in air using a 100 mW/cm2 beam for 1 to 5 minutes. In the present study we inscribe two sinusoidal gratings and coat the surface with a 20 nm thin film of gold. Light incident onto this structured surface is coupled into a surface plasmon when the appropriate angle of incidence and wavelength are selected. The coupling condition can be observed in the reflection spectrum from the surface. A dispersion curve for the plasmon propagation can then be produced by studying the reflection spectrum as a function of the angle of incidence. By using two gratings as couplers, a surface plasmon standing wave can be produced for a selected incident light wavelength.

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.
