Abstract

fetched live from OpenAlex

In modern WDM/DWDM based optical networks, wavelength division is very important. Bragg gratings are used in many devices to reflect, and thus isolate, specific wavelengths of light. Chalcogenide glasses can be used to create such gratings due to photorefractive effects that take place when illuminated with near bandgap light. We have created holographic Bragg gratings in As2Se3 films by using a HeNe laser to illuminate the glass in a periodic interference pattern. Refractive index changes of 0.009 have been measured.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
