Series‐coupled microring resonator filters with embedded semiconductor optical amplifiers
Bibliographic record
Abstract
Abstract Back reflections from series‐coupled optical microring resonator filters caused by waveguide discontinuities are numerically investigated and optimized. The focus is on small discontinuities, such as those that can be expected from GaInAsP/InP‐based semiconductor optical amplifiers (SOAs) embedded in ring resonators. Significant improvement of the return loss is obtained when the length of the SOA is appropriately chosen. The design principle is applied to both all‐pass (two‐port) and add/drop (four‐port) filters. The sensitivity of the design to fabrication parameters is discussed. © 2004 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
