Modeling and design of GaAs traveling-wave electrooptic modulators based on capacitively loaded coplanar strips
Bibliographic record
Abstract
GaAs traveling-wave electrooptic (EO) modulators based on capacitively loaded coplanar strips (CPSs) have been extensively modeled, and near-optimal designs are presented. The modulator operates in a push-pull mode, and the electrodes are coupled capacitively in series via the doped under layer. The best design reported herein has asymmetric CPSs 2 cm long and generated a figure of merit of about 9.36 GHz/V. This figure of merit is an improvement by a factor of about 2.5 over the best design reported to date for this modulator architecture. Modulator bandwidths in the range of 40-70 GHz (3 dB electrical) are predicted for various designs; the corresponding optical bandwidths are in the range of 75-110 GHz (3 dB optical).

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
