Fabrication of waveguide devices by UV photopatterning of fluorinated poly(arylene ether ketone)s containing tetrafluorostyrol moieties
Bibliographic record
Abstract
This work demonstrates waveguide devices based on a novel photocrosslinkable fluorinated poly(arylene ether ketone). A new molecular design has enabled waveguide fabrication to be achieved for the first time using this kind of polymer, through direct UV patterning and a wet-etch process, which is faster and more convenient and economical than the process based on standard reactive-ion etching that has been applied to previously reported poly(arylene ether ketone) materials. High-quality waveguides with smooth, well-defined sidewalls have been produced, and optical splitter devices based on directional coupling are demonstrated. Optical characterization of these devices suggests that the waveguide quality is comparable to that of waveguides fabricated using a dry-etch process, and the experimental data obtained from the fabricated optical splitters are in excellent agreement with theoretical predictions.

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.
