Silicon ring resonator based optical phase shifter for higher order modulation formats
Bibliographic record
Abstract
In this paper, we demonstrate a silicon-on-insulator (SOI)-based optical phase shifter that combines the through and drop ports of a silicon add-drop microring resonator (MRR) modulator. The measured intensity spectra for different bias voltages show that we achieve a 4.29 dB reduction in maximum intensity variation compared to the maximum intensity variation observed at the through port for a ∼2 π phase shift. We also recovered the phase spectrum by placing the optical phase shifter in one arm of an integrated Mach-Zehnder interferometer (MZI) structure. We achieved a full 2 π phase shift of a continuous wave (CW) optical signal with a maximum of ∼4.38 dB of intensity variation. Finally, we created the constellation map of an 8-ary phase-shift keying (8-PSK) data signal based on the recovered phase and the intensity at different forward bias voltages.

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.
