Monolithic InGaAs/InGaAsP electro-absorption intensity modulator fabricated using low energy arsenic ion implantation induced intermixing
Bibliographic record
Abstract
10-channel monolithic multiple wavelength electro-absorption (EA) modulators have been fabricated onto a single chip using a one-step quantum well intermixing technique based on As/sup 2+/ ion implantation through a graded thickness silicon dioxide mask. Each individual modulator has a dimension of 400/spl times/500 /spl mu/m/sup 2/, 50 /spl mu/m width of active window, 500 /spl mu/m cavity length and 20 /spl mu/m width of isolation trench. The EA intensity modulators were characterized at room temperature using end-fire-coupling technique. Samples used in this study had a InGaAs/InGaAsP MQW (five quantum wells) laser structure grown by metal-organic vapor phase epitaxy and were of the form of a stepped graded index heterostructure.

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.
