Abstract

fetched live from OpenAlex

Phase-change materials (PCMs), capable of non-volatile electrically or optically induced transitions, are being actively explored as a promising option for use in silicon photonic neuromorphic integrated circuits and compact modulators in telecom networks to overcome the limitations in footprint and power consumption imposed by the utilization of weak and volatile thermo-optic effects in current architectures. We present the first-ever broadband measurement of the thermo-optic effect in a number of widely explored chalcogenide PCMs across visible to telecom frequencies. Our measurements show that beyond their non-volatile phase change properties, PCMs also possess giant switchable broadband thermo-optic coefficients.

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.
