Abstract
A widely-tunable laser source (WTLS) is discussed that is particularly well-suited for use in a passive component analyser, which is based on a novel design incorporating two distinct resonant cavities sharing a common tuning element and a common optical output. This design comprises a polarisation-maintaining fibre, two semiconductor optical amplifiers, a low-loss tunable filter and wavelength-independent fused couplers. The WTLS can be continuously tuned over the O-, E-, S-, C- and L-bands with an output power greater than −12 dBm from 1250 to 1637 nm and a peak power of 4.5 dBm. The laser exhibits a signal-to-noise ratio of greater than 80 dB over almost all the spectral range when measured with an optical spectrum analyser having a resolution bandwidth of 1 nm. Its effective 3-dB linewidth is less than 7 GHz.

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 it
