Abstract
We propose and analyze a new technique for optical pulse shaping that uses fiber Bragg gratings, which overcomes the depletion effects associated with long uniform gratings operating in the weak-grating limit (Born approximation). Our approach requires a simple linear reflection of the original input pulse to be shaped from a suitable apodized linearly chirped fiber Bragg grating and is based on the fact that, under certain conditions, the spectral and temporal reflection impulse responses of the grating are scaled versions of its corresponding apodization profile. Temporal waveforms in the picosecond/nanosecond regime can be accurately synthesized with this approach.

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 it
