Abstract
We report on the controlled transfer of single rolled-up semiconductor microtube-based optical cavities from their host substrate to a foreign one. Such microtube devices, with diameters of ~5 ¿m, wall thicknesses of ~50 nm, and lengths of >100 ¿m, are fabricated by selectively releasing a coherently strained InGaAs-GaAs quantum-dot layer from the handling GaAs substrate. With the use of fiber abrupt tapers inserted into two ends of the tubes, rolled-up microtubes are lifted off from the substrate and subsequently transferred, with a precisely controlled position, onto the cleaved facet of a single-mode fiber. The resulting devices exhibit strong coherent emission at room temperature and may lead to integrated micro- and nanoscale lasers with greatly simplified packaging.

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
