Abstract
We propose and demonstrate a high-performance suspended grating coupler on ultra-thin X-cut lithium niobate on insulator (LNOI) for fully-etched photonic devices. The optimized design achieves exceptional coupling efficiency (-3.5 dB at 1546.24 nm), a broad bandwidth (1 dB bandwidth of 70 nm and 3 dB bandwidth exceeding 90 nm), and robust fabrication tolerance. This work addresses a critical challenge in integrated photonics by enabling efficient grating couplers on ultra-thin LNOI platforms, thereby providing a practical and scalable solution for coupling light into photonic crystal waveguides and other suspended photonic devices.

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
