Promising intracavity mode-locking device: A strained GaInAs/AlInAs saturable Bragg reflector grown by molecular-beam epitaxy
Bibliographic record
Abstract
A strained GaInAs/AlInAs saturable Bragg reflector (SBR) was fabricated from layers grown by molecular-beam epitaxy. The device consisted of nominally 25 periods of GaAs/AlAs Bragg structures incorporating double GaInAs/AlInAs quantum wells latticed matched to InP. The SBR was measured to be more than 99.5% reflective from 1410 to 1525 nm. The structural parameters for the sample were obtained from high-resolution x-ray diffraction rocking curves. The quantum wells exhibited partially relaxed interfaces where the relaxation was characterized by misfit dislocations. The photoluminescence measurements showed a lack of well-defined band edges and exciton structure at room temperature. Luminescence peaks were obtained at liquid-helium temperature, corresponding to heavy-hole and light-hole related exciton levels. The fast recovery of the SBR nonlinear response was explained by the misfit dislocations, which act as nonradiative recombination centers.

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.
