L‐band erbium‐doped fiber ring laser with a wide tuning range
Bibliographic record
Abstract
Abstract A ring erbium‐doped fiber (EDF) laser with an additional EDF saturable absorber operating in the L‐band can produce dual‐wavelength optical bistability. The bistabilities of the two wavelengths evolves in antiphase; the dual‐wavelength bistable behavior can be controlled by the cavity loss and adjusted by varying the EDF length. This property is used to switch the laser between the two wavelengths by triggering the pump source. The typical switching time is about 4–15 ms. By making use of the bistability, the laser may be tuned across the entire L‐band by using only ordinary commercial tunable fiber Bragg gratings (FBGs). An output dynamic range of 7.5 dB and an optical signal‐to‐noise ratio of 70 dB have been achieved. © 2003 Wiley Periodicals, Inc.

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.
