Abstract

fetched live from OpenAlex

We present the integration of a defect-enhanced photodiode with high sensitivity at 1550 nm with a silicon waveguide structure formed by the LOCOS (LOCal Oxidation of Silicon) process. The defects are introduced through a 4 MeV Si+ implantation followed by thermal treatment at 200–500 °C to form a sub-bandgap photo-response. A 100 nm polycrystalline silicon layer forms a self-aligned contact to the top of the ridge waveguide and provides efficient extraction of generated carriers. Processing conditions and device structure design have been varied to determine their influence on responsivity, insertion loss and leakage current. A 6 mm long optical power monitor is presented with responsivity of approximately 47 mA W−1 at −5 V bias for an absorption of 12 dB (∼0.003 A W−1 dB−1).

Full frame distilled prediction

Teacher imitation

Not 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.
