A WDM Capable SiP Polarization Compensator That Isolates the Carrier Laser
Bibliographic record
Abstract
We demonstrate a SiP O-band transmitter, autonomously compensating for any injected laser state of polarization (SOP), achieving net 105 and 154 Gbps PAM4 and PAM8 transmission below the Hard-Decision and Soft-Decision FEC thresholds, respectively, with the carrier laser remotely connected to the transmitter over 1 km of single-mode fiber. To enable autonomy, a feedback gradient descent algorithm is implemented, with the starting point determined by the polarimeter, to mitigate the polarization-dependent loss on the device. Additionally, the wavelength dependence and performance of the transmitter are experimentally determined to increase the effective net rate. An emulated WDM transmission was then performed at the 1304.58 nm and 1309.14 nm wavelengths, achieving net 224 and 307 Gbps OOK and PAM4 performance, below the Hard-Decision and Soft-Decision forward error correction thresholds, respectively.

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.
