Infinity Additive Manufacturing of Polarization Maintaining Fibers for THz Communications
Bibliographic record
Abstract
A polarization-maintaining fiber was developed for communication applications within multi-channel and polarization-division multiplexing modalities. The fiber was designed for signal transmission at 128 GHz carrier frequency. It was 3D printed using a 35° inclined nozzle that enables length-unlimited fabrication of terahertz fibers featuring complex transverse geometries. More importantly, a significant reduction (~25%-40%) in fiber transmission loss was achieved after annealing the fabricated fiber at a temperature close to its melting point, resulting in the reduced fiber losses (by power) approaching ~5-10 dB and ~7-11 dB over 110–150 GHz for the two orthogonally polarized modes. The communication demonstrates show that the signal transmission with bit error rates of ~10-11-10-5was supported at 128 GHz over 1–6 Gbps by the two orthogonal modes of the annealed fiber. The experimental characterization demonstrated the promising prospect of such a novel technique for the fabrication of advanced THz fibers for fiber-assisted communication applications.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
