Abstract
We report on the achievement of strong coherent emission from GaAs-based single-walled spiral microtubes, wherein photons are localized in an ultrathin (approximately lambda/25) region embedded with self-organized InGaAs quantum dots. The emission spectra measured at 300 K are characterized by a regular sequence of sharp optical modes with a maximum Q factor of approximately 2500 and separation of approximately 7 meV. The three-dimensional confinement of photons is made possible by the epitaxially smooth tube surface as well as an engineered surface geometry, achieved using a single photolithography step. The experimental results are analyzed using an equivalent planar dielectric waveguide model.

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
