Abstract
Two cascaded semiconductor optical amplifiers (SOAs) with different bandgaps are proposed as an all-optical switch based on cross-gain modulation (XGM) to reduce the pattern effect inflicted by a carrier-lifetime-related long-lived gain recovery tail. We numerically investigate the device gain recovery dynamics in such setup excited by 100 Gbit/s pseudorandom return-to-zero control signal at 1520 nm for different probe wavelengths. The preliminary simulation results indicate that the pattern effect in a SOA in which control pulses are localized in gain region can be reduced by a concatenated SOA in which control pulses are situated in the absorption region. This compensation principle is always valid when the bit rate is beyond 100 Gbit/s.

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
