Abstract

fetched live from OpenAlex

Optical communications, remote sensing, particle trapping, and high-resolution imaging are a few research areas that benefit from new techniques to generate structured light. We present a method of generating polarization-structured laser beams that contain both full and partial polarization states. We demonstrate this method by generating an optical beam that contains every state of partial and full polarization. We refer to this beam as a volumetrically full Poincaré beam to distinguish it from full Poincaré beams, which contain all states of full polarization only. In contrast to methods relying upon spatial coherence to generate polarization-structured beams with partial polarization, our method creates well-collimated beams by relying upon temporal coherence.

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.
