Abstract
A silicon photonic integrated frequency-tunable optoelectronic oscillator (OEO) is designed, fabricated and experimentally demonstrated. Three key components including a high-speed phase modulator (PM), a thermally-tunable high-Q micro-disk resonator (MDR), and a high-speed photodetector (PD) are monolithically integrated on a silicon photonic chip. The joint operation of the PM and the MDR corresponds to a microwave photonic filter (MPF) with an ultra-narrow notch that is thermally tunable. By feeding the output signal from the MPF to its input port through an electrical amplifier to provide a sufficiently large gain, the MPF becomes an OEO and oscillation starts. A microwave signal with a frequency tunale from 3 to 7 GHz is generated. The phase noise of a generated microwave signal at 5.4 GHz is measured to be -80 dBc/Hz at an offset frequency of 10 kHz.

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
