Semiconductor optical parametric generators in isotropic semiconductor diode lasers
Bibliographic record
Abstract
We report on the characteristics of an intracavity semiconductor optical parametric generator in multiple-quantum well AlGaAs/InGaAs Bragg reflection waveguide lasers emitting between 986 and 995 nm. The cavity of the laser is phase-matched for down-conversion of pump photons to a signal between 1739 and 1767 nm and an idler between 2235 and 2328 nm. The normalized conversion efficiency is calculated to be 1.23×103 %W−1cm−2 above laser threshold and 1.25×104 %W−1cm−2 below threshold. The demonstrated device is potential for the realization of integrated parametric devices such as electrically pumped entangled photon-pair sources and optical parametric oscillation, where quantum optical effects can unfold.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
