Abstract

fetched live from OpenAlex

Prospects of Erbium doped Silicon nano-crystal system in achieving on-chip optical amplification and lasing performance have been studied. The mechanism of energy transfer from excitonic recombination in nano-crystals to erbium atoms, and its competition with all non-radiative routes have been analyzed. It is found that the density of nano-crystals play a crucial role in achieving the level of population inversion of erbium excitation. Dependencies of nano-crystal density, erbium density and pumping power have been correlated. Nano-crystal densities of the order of the 6×1018cm−3 with erbium incorporation in the range of 1020 cm−3 has been found to be resulting in the achievement of population inversion at optical pumping power of the order of 200 mw. High quantum efficiency of energy transfer to erbium atoms has been estimated for incorporated erbium densities beyond 1020 cm−3.

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.

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.
