Silicon nitride (SiN<sub>x</sub>) plasma deposition on optical fiber sensors: coating symmetry perspective
Bibliographic record
Abstract
This paper discusses the influence of coating long-period gratings with a silicon nitride thin overlay on the grating’s spectral response. The overlays have been obtained with a radio frequency plasma enhanced chemical vapor deposition method. During the experiment, the structures were positioned on various heights over the electrode using specially developed sample holder. The results of the experiment show that the investigated long period grating structures have increased their sensitivity to variations of external medium refractive index in the range of n<sub>D</sub>=1.33 to 1.43 RIU. The relation between the height at which the long period grating was placed over the electrode and the deposited overlay symmetry is discussed. The highest sensitivity of 2080 nm/RIU has been observed for the grating placed at the highest positions of the holder out of the examined range of 3 to 8 mm over the electrode. This overlay also shows the highest symmetry around the fiber.

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.
