70-nm tunable single-longitudinal mode erbium-doped fiber laser
Bibliographic record
Abstract
This paper presents experimental results on a 70-nm-wide, quasi-continuously tunable, single-longitudinal-mode erbium-doped fiber (EDF) laser. The cavity incorporates three tunable band-pass filters; a bulk grating based tunable band-pass filter, a fiber-ring-cavity filter, and an auto-tracking saturable absorption induced grating filter generated by an un-pumped EDF. In our experiment, this laser produced a single longitudinal mode oscillation between 1510 nm and 1580 nm, an output power of 0.5 mW and a tuning step of less than 0.2 pm. Optical frequency jitter was less than 0.8 pm and the signal to source spontaneous emission ratio (S/SSE) was higher than 60 dB. A tunable single-longitudinal-mode L-band fiber laser will also be discussed in this paper.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
