Abstract

fetched live from OpenAlex

We presented design, growth and fabrication of the InAs/InP quantum dot (QD) gain materials and the basic performance of the Fabry-Perot QD lasers as compared with the quantum-well (QW) lasers with the same doped materials and structures. By using those QDs we have developed several ultra-low intensity and phase noise coherent comb lasers (CCLs). We have used a 25-GHz QD C-band CCL to successfully demonstrate 10.3 Tbit/s (16QAM 56×23 GBd PDM) back-to-back coherent data transmission for coherent networks and 56×50 Gb/s PAM-4 back-to-back transmission with capacity of 2.8 Tbit/s at a symbol rate of 25 GBaud for data center applications.

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.

Not 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.
