Abstract
An <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -band polarization-independent reflective semiconductor optical amplifier (RSOA) is demonstrated for the first time. Optical gain of greater than 21 dB and gain flatness better than 4 dB is achieved over the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -band. The polarization-dependent gain estimated using a polarization resolved spectrum is less than 1 dB over the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -band. The measured output saturation power is -1.0 dBm and the noise figure (NF) is 10 dB for the packaged device. The 3-dB frequency bandwidth for the device is 1.3 GHz making it suitable for 1.25-Gb/s modulated wavelength-division-multiplexed passive optical network networks. Further, the saturation power and the NF of the RSOA were compared with an SOA of identical length.

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
