Abstract

fetched live from OpenAlex

In this work, we report on all-silicon waveguide photodetectors utilizing surface state defects and bulk defects to sensitize the silicon to sub-bandgap light. The detectors are foundry fabricated, waveguide-integrated p-i-n junctions with post-processing consisting of HF acid exposure, ion implantation, annealing, or a combination of the three. HF exposure increases the photoresponse of the as-received detectors due to the increase in unpassivated surface states. The efficiency of surface state detection is greater than that for bulk defect detection in terms of mode overlap with the defected volumes of the silicon waveguide. Detectors in all cases have a 3dB bandwidth of 7GHz.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
