Abstract

fetched live from OpenAlex

Co-packaged optics leads to significant power reduction by placing the electronic and photonic chiplets in a single package. An integrated electro-optical substrate made of glass with optical waveguides, through vias and electrical redistribution layers inside a single-sided cavity enables fine-line electrical routing and low-cost assembly. Existing glass and thin film technologies were evaluated and combined into a single process stream including photonic assembly. Photonic chips with silicon nitride waveguides were optically coupled to integrated low-loss (<0.1 dB/cm) glass waveguides with minimum loss of 0.65 dB achieved by fiducial alignment and pick-and-place assembly.

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.
