Abstract
We investigate the modal gain seen by transverse-electric (TE) and transverse-magnetic (TM) modes of bulk and multiquantum-well (MQW) lasers given a nonuniform distribution of active region carriers. We find that the dependence of modal gain on the nonuniformity of carrier profile differs for TE and TM modes. This experimentally observable phenomenon is proposed as a measure of carrier density nonuniformity. We discuss the importance of the confinement picture for TE and TM modes, in the generalized presence of some asymmetry, in assuring injection-level independent polarization insensitivity in semiconductor lasers and optical amplifiers.

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 it
