Abstract

fetched live from OpenAlex

We report on the fabrication, characterization and integration of semiconductor microtube lasers on silicon. These microtubes are fabricating using standard photolithography techniques on epitaxially grown strained bilayer films, and show remarkable spectral properties attributable to whispering-gallery-mode type optical resonances. We have demonstrated coherent emission coupled to the optical microcavity modes in both GaAs/InGaAs and InGaAsP microtubes with embedded quantum dots. Furthermore, the GaAs/InGaAs microtubes have shown room temperature, continuous wave lasing. The microtubes can be transferred to any foreign substrate without affecting their optical properties. Work is in progress to couple the tubes with integrated silicon-on-insulator waveguides.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
