Dispersion-tuned Mode-locked Optoelectronic Oscillator
Bibliographic record
Abstract
A dispersion-tuned mode-locked optoelectronic oscillator (OEO) is demonstrated for the first time. A flat and highly chirped microwave photonic filter with a large bandwidth within the OEO, which is essential for dispersion tuning, is realized by employing a sliced amplified spontaneous emission (ASE) source and a 1.1 km dispersion-compensating fiber (DCF). A recirculating loop is introduced to ensure single-mode oscillation when the OEO operates in the free-running state. In the mode-locked state, as the modulation frequency is swept from 10.3042 MHz to 10.3122 MHz, corresponding to approximately 58-order harmonic mode-locking, the OEO output frequency exhibits discrete tuning from 4.08 GHz to 5.08 GHz, with a total of four distinct frequency steps. This demonstration opens up a new approach to frequency control in OEOs.

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.
