Abstract
Abstract An overview is presented of recently developed light‐mediated methods for ferroelectric domain engineering of lithium niobate single crystals. These methods include light‐assisted poling , UV laser‐induced inhibition of poling , and all‐optical poling . In addition to the primary application of ferroelectric domain patterns, namely the realization of non‐linear optical devices, the ability of transferring a domain pattern into a topographical structure by domain selective etching allows also for surface structuring of lithium niobate. This intertwining between ferroelectric domain patterns and surface topography has been used to fabricate exquisite micro‐structures based on unusual domains generated purposefully by these light‐mediated methods.

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
