Erbium Doped Silicon Nanocrystal: for Optical Amplification and Lasing
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
