Abstract
This paper has demonstrated a 40-Gb/s low-driving-voltage electroabsorption modulator (EAM) having InGaAlAs/InAlAs multiquantum-well active core. A narrow core buried with polyimide provides a strong optical and electrical confinement, resulting in a maintained large extinction ratio (ER) and an increased 3-dB down frequency. The fabricated EAM shows a 3-dB down frequency as large as 46 GHz, even for the active-core length as long as 200 /spl mu/m. The EAM operates at 40 Gb/s with an RF ER of 10.5 dB at a driving voltage as low as 0.79 V.

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
