Orthogonal polarization multi-wavelength Brillouin random fiber laser with triple Brillouin frequency shift space
Bibliographic record
Abstract
A novel multi-wavelength Brillouin random fiber laser with the channel space of triple Brillouin frequency shift and high polarization orthogonality between adjacent wavelengths (TOP-MWBRFL), to the best of our knowledge, is experimentally demonstrated. The TOP-MWBRFL is structured in a ring form by cascading two Brillouin random cavities of single-mode fiber (SMF) and one Brillouin random cavity of polarization-maintaining fiber (PMF). Based on polarization pulling properties of stimulated Brillouin scattering in long-distance SMFs and PMFs, the states of polarization (SOPs) of lasing light from SMF random cavities are linearly bounded to the SOPs of local pump light, whereas the SOP of lasing light from the PMF random cavity is strictly clamped on one of the principal axes of the PMF. Thus, the TOP-MWBRFL can stably emit multi-wavelength light with high polarization extinction ratio (>35dB) between adjacent wavelengths without precise polarization feedback. In addition, the TOP-MWBRFL can also work in one polarization mode to stably lase multi-wavelength light with SOP uniformity as high as 37 dB.

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.
