Experimental and theoretical characterization of multimode fiber Bragg grating external cavity lasers
Bibliographic record
Abstract
In this paper both statistic and dynamic behaviors of the multimode fiber Bragg grating external cavity lasers (MMFBG_ECL) have been studied experimentally, and simulated numerically by time domain traveling wave (TDTW) rate equations. Experimentally, multiple wavelength selection has been realized by offsetting the coupling between the laser diode (LD) and the MMFBG. Small signal modulation responses at these wavelengths have been measured and over 8 GHz modulation bandwidths have been demonstrated at several wavelengths. Numerically, the TDTW model has been employed to simulate the multiple wavelength lasing selection and L-I curves. Comparison between single mode fiber Bragg grating external cavity lasers (SMFBG-ECL) and MMFBG-ECL have been addressed. In addition, steady experiments and numerical simulated are made to verify our numerical model.

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.
